I strangely relate to that feeling of Java having a place in your heart. I can easily list all the reasons I don’t like Java and yet sometimes I feel homesick for it. Makes no sense.
There are many languages I'd rather write code in, but Java really isn't as bad as people say it is. Java 1.5 and lower was absolutely awful, but things started getting better in Java 7 and especially 8. Now it actually feels like a modern language.
After spending a lot of time in the TS world, you start to realise how nice it is to have explicit interfaces at run time, nominal sealed classes, and real enums with properties and method and whatever. The only issue is that the Java world is the opposite of the JS world, instead of hype driven development there’s still companies on Java 8 who don’t trust recent LTS versions still. Oh and that exception situation is weird. Kotlin’s a nice sweet spot.

Correction at 19:05 : It is the other way around. You have to read it from right to left. Here is a breakdown: const int* const foo(const int* const& ptr) const 1. const int* const Means that the method returns a const pointer to an int that is const 2. const int* const& ptr Means that the method takes a reference to a const pointer which points to an int that is const as an argument 3. const Means that the method cannot change member variables (unless they are marked as mutable or you cast away the const using const_cast)

@@barongerhardt yeah mutable is terrible except in lambdas, and people use it for the worst reasons.

Yep I noticed the same! Not writing in C++ every day though, but these things I know. But what I do not know, is the situation in TypeScript. Is it opposite there? Because that may of course be a large source of confusion then. Many C family languages have a preceding type notation style, also including Java, C# and Go, but some are more into the trailing form. I know that like Rust, TS does it's in types trailing notation. So I can really imagine a difference with the const keyword as well.
@@jongeduard Constness is different in JS/TS land. In JS/TS `const` is used to define a const reference to an object. It's the reference that cannot change, not the object that it points to. Whereas using `let` allows you to later change the reference. In both cases, you are free to change the properties of the object being referenced. In TS there's `readonly` which you could apply to properties. This is what statically checks and prevents you from modifying said property. There's also `as const` which is used to cast all properties of an object as readonly. I believe it's also used to define literal types. In JS, there's also Object.freeze() which prevents modification of an object's properties. All in all, a different language. Don't forget that JS is an embedded language and can't do anything practical on its own. Its core and implementation resides in C++ (V8 in Chromium based browsers for ex.) TS is just a static analyzer on top.

I don't know if anyone here reads the comments, but Python is the best language for getting out your ideas. If I have an idea for a program, or a basic app I can do all of it in Python test it maybe even stick with just that if it's good enough. Then once I have everything down, and looking right I can go ahead and recode everything into a language that may be better for what I am trying to accomplish like C.
Pin on a pointer type is a promise that you can depend on what's in a pointer staying valid as long as the pointer is valid. Unpin on a pointee means that it doesn't need that promise, and that you can move it out anyway. Pin is needed for generic/library code to be able to trust that it can keep interior pointers around, in particular for async code to keep references to other stack variables around at an await point. You can commonly provide it either by pinning an existing value to the stack with pin!, or moving it to the heap with Box::pin(), both of which prevent you from moving the value out. Unpin means a type doesn't need to be pinned, or equivalently, that you can safely remove the pin. It can be used either to assert than a type doesn't require pinning, or to allow generic code to let callers have a nicer API if they know it doesn't matter for some type, as methods can be conditionally available on a generic parameter implementing a trait. A confusing detail is that pinned pointers are themselves a good way to get an Unpin from a value that isn't already Unpin: this is because if it's already pinned, you don't need to work about adding any more pinning.
LUA is incredibly useful if you ever need to embed a scripting language into an application. And there are a lot more reasons to do this than the average lay person might suspect.
I believe that since all of Valve's games, support modding and Lua is the main scripting language used for them. So I can assume that you can integrate Lua modding in your game easier than with other languages.
C++ standard library is super ugly for two main reasons: it must only create identifiers defined by the standard or with the reserved double underscore or underscore Capital patterns; and it often wants to share behavior without hitting the C++ issue where each base class must have a separate address by using recursive template definitions and other metaprogramming techniques. They don't actually write the code with the underscores, btw, it's run through an uglifier script.
There are some "things you can do in JS" that TS by default won't let you do even though it is actually safe. But thats more that ALL JS runtimes have certain standard library things behave one way but the spec is more strict. And TS has those all typed to the spec.
I'm using C++ and LUA daily since many years, so they're both S-Tier in my programming languages tiers list (for completely different reasons). No real opinion on other languages since I rarely use them, ofc there is what I call the "classic webdev duo" (PHP and JS) I use sometime. Python is also great to make quick program and there is a big community around.
I learned from one UA-camr that to read C++ consts if it's in the beginning (which means there's nothing to its left to make it const) then it makes the first thing to its right a constant, but wherever else you put it it makes the thing to its left constant
We need to just stop using Javascript for anything other than front-end scripting. Y'know, the thing it was designed for. It's easy to say JS is a trash language when you use it in a domain it isn't meant to be used. It's like trying to use Java on something that isn't a blueray player, or Python on a computer. When you use a language not how it is designed to be used, it'll seem like trash.

I subscribed a few days ago. And I just love it when Lua is recognized. I thought I was the only one who loved it locally. (Brazil Mentioned: I'm not from there but dammit! Love that they are mentioned). Then I went to the smoke shop next door from my apartment. All of us college dev's hang out there. Yup. Lua has its fans. Python is my first that I mastered, but Lua is what I first picked up. And I went back to it after success with Python. Lua needs more LOVE....(return a 1 if you know the double meaning of that).
For those curious, std::pin simply means the memory address is locked, while std::unpin will allow it to change memory locations. For example, if you want rearrange the data to sit in memory better, you can pin specific values to an address and know that they will always be in that location. Not far from describing pinning a note to a cork board. Now, from what I understand of this, it sounds like a way to memory map. I would think this would be more bare metal, but I don't know what it could be used for outside of memory mapping.
"Features are for the weaks", man i got you. Don't be afraid to use pointers if necessary. Your responsibility as a programmer is to write good software. Prioritizing safety and an easier path can make you a weaker programmer
For rust, I think the pinning is the making a object constant without declaring it as such when its created or its value defined, so that another async op needing it, can set it to be a static object, before returning and it can get unpinned
“Php is only useful for the web and even that is easily done with other languages” is one hell of a take lol You could do web in other languages/stacks, and have an objectively worse time, all the time. PHP Lives and Dies by the Request/Response life cycle which is 👌 perfect for delivering web pages. You know what else is fantastic as a Request/Response? CLI tools. Yes. Absolutely. PHP is so shocking excellent at making CLI tools I’ve stopped using python and C++ in favour of it. I wouldn’t advocate for an S tier or anything but it absolutely does not belong in E lol it’s way too useful for that
Many years ago I wrote quite a lot of CLI tools in PHP… Why? I didn’t want to add any additional software onto the server, and PHP can handle everything I needed it to do. It does fantastic at CLI tools, just like a web page, feed it options (query params) and let it generate a response. Who said it *needed* to be HTML in the output?
Python as a slightly better Bash is S+ tier. Python as an actual programming language to build complex software system is the biggest drum of b&llsh$t humanity has ever conceived.
I piddled around in BASIC as a kid, and in high school I took a class where we did Pascal on greenscreen dumb terminals. But my first nontrivial programming language was C. I remember the day I learned about pointers. I had a massive headache. Then I added C++ to my toolkit. I liked that wrapping stuff in objects made it easier to pass larger payloads of information around. I did some Java in college for EE (along with some more C, C++, and assembly), and I've dabbled in Python, JavaScript, PHP, MATLAB, and some other esoteric stuff (LabVIEW, anybody?). But when I need to actually get stuff done, I always go back to C or C++. My younger brother got a CS degree and learned entirely in C#. Then he got a job and saw "malloc" in code he was maintaining. He didn't even know what it was.
But a better way to write const in c++ is "T const* const" (or for example "T const&") It makes much more sense, because you can literally read it (from right to left) as "const pointer to a const T"
I mean, there is code that will make typescript complain but is allowed in javascript, such as this: const a = 0; a = "0"; It will still "transpile" the code to javascript, but it will also tell the user that there is an error. Not sure if you can call it a superset if it doesn't think it's valid.
im someone who is pretty basic in there programing ability, and I recently tried rust, go and c# (from allways using js and python) and I have to say that c# is really nice, if I'm going to use types I might as well use a language where its built in and has great intelisense instead of typescript which I never got the hang of.
Java changed my life 25 years ago. Rescued me from Window's client server hell and cured me of my Smalltalk fantasies. It has had the greatest impact on the software engineering profession than anything else in history.
@@keldencowan At the time there were three vendors of Smalltalk. The language was awesome. The IDEs they provided were awesome. But the final product was mostly unusable. Connecting to various databases was expensive or not possible. The real problem was they couldn't generate an executable application file with a reasonable footprint. Java came along and gave as an OO language that could do everything for everyone. In those days we made desktop client server apps using PowerBuilder, Delphi(me), and a little later C++ with Visual Studio. They only worked on Windows and required sophisticated UI programming and were a hassle to deploy to users and get them working for everybody.
For use as well. We were in hell with Windows client back in the day. Moved to Java and we were happy. Still use it now. We're doing Data Engineering with Databricks all running on the JVM. Super cool stuff.
If you're consistent, there's no confusion on const-correctness: int const * const foo(int const * const & ptr) const I never allow the "left-to-right" exception to const-correct reading rules.

9999999999999999 becoming one higher is not a JS problem but just yet another general FP number limitation as defined by IEEE 754. If I cast this integer to a double sized floating point in any language, for example in Rust via 9999999999999999 as u64 as f64, I see the exact same thing happening. Many things in JS are trashy design, but FP precision related limitations are not. I liked the video! Though I think C# and actually also Java should really be above TS.
@@KangoV Prime is a smart guy, I expect better. The thing with both Java and C# is that both languages have evolved a lot, things have changed. Yes they still have some legacy things in their design too, but it's so much better than many other languages from before. And issue is that there is still a lot of poorly written old enterprise source code around, and I know that too, I know some 20 year old C# code really well from work. But it's unfair to judge the modern version of these programming languages for that.
"I think everyone's first language is special" might be why I favor the use of whitespace and indentation in python. VB was my first language, and though I don't care for it and haven't used it in ages, writing python feels so much like vb it's unreal.
Templates in c++ are compile time executed and therefore pretty ugly to debug. But they are lightning fast. Together with the STL they provide a sweet spot between performance and usability. Try to outperform the STL in any task. It is very hard and for most impossible.
If you're not extremely careful, they blow up in code space which thrashes your instruction cache. But in the hands of an artist, you can achieve performance not far below hand-coded assembly language.
16:04 - idk I think it would make sense, I think you're thinking about the end code, maybe this like works on kernel. (speculation) Like it's a feature included to allow the compiler to prevent you from compiling moving memory accidentally. Still if it's that, you know Rust right, do you need a feature for that?
I don't get the love for C over C++, you can program in C++ exactly like C and benefit from stronger type safety and, if you choose, make use of built in classes, references, templates etc.
I think the hate is mainly from when you have to interface with someone else's code abomination. Some people see the language feature set, and have to use the whole language feature set.

@@isodoubIetit’s good to be different, but that’s a wild take, man. Mathematics (and therefore science) notation has been 1 indexed since Newton and Leibniz. Literally everything is based on that, from matrices, to series, to graph theory to everything that uses numbers…
@@alst4817 It's not at all "wild". It's a perfectly normal and reasonable take. The arguments for 0 indexing have been made in extreme clarity (by Dijkstra) in the 80s and they don't really depend on setting, so it'd be really surprising if math happened to be different. Try to manipulate any sort of nontrivial series summation with 1-indexing vs 0-indexing, and then tell me which one is easiest. Or try to index into an n-dimensional array. Yes, people in the 1600s didn't know better. That's no excuse for making the wrong choice in the 21st century.
The c++'s std::variant definition mess showed in the video is actually not that horrible (pretty much everything else about std::variant is, though). Most of the typing is only namespace resolution. Then, the goal is to enable or disable the usual copy/move constructors/assignment operators based on the properties of the types in the variant. It makes the top level of std::variant trivial as all operators can now be defaulted. Private inheritance is a very usefull metaprogramming feature to conditionnally define member functions (and sometimes variables) based on template parameters properties.
C is god tier if and only if you are willing to spend years of your life perfecting your understanding of all of its underlying elements. If literally anybody else uses it, the codebase will eventually become garbage. By the way, at 19:22, the first const means a constant int, and the second const means a constant pointer.
Variant is an union. Nothing too complicated. Well, if you add things like refcounted IUnknown/IDispatch and especially the SAFEARRAY horror, yes, it can suck. Sometimes. But hey, VB6 is built on this.
honestly i don't understand the dislike towards PHP. The only reason for the hate is it's history. Mainly the fact that the wrong "developers" were using it back in the day and produced some crappy code (ok to be fair it wasn't the best langauge but big changes happen with PHP5). It's not the language to blame is those using it. Leave someone who doesn't know a thing to writte some code on the most secure language and they will mess up big time for sure (yeap i know PHP defender here lol).

Yep I noticed the same! Not writing in C++ every day though, but these things I know.
But what I do not know, is the situation in TypeScript. Is it opposite there? Because that may of course be a large source of confusion then.
Many C family languages have a preceding type notation style, also including Java, C# and Go, but some are more into the trailing form.
I know that like Rust, TS does it's in types trailing notation. So I can really imagine a difference with the const keyword as well.
@@jongeduard Constness is different in JS/TS land.
In JS/TS `const` is used to define a const reference to an object. It's the reference that cannot change, not the object that it points to. Whereas using `let` allows you to later change the reference.
In both cases, you are free to change the properties of the object being referenced.
In TS there's `readonly` which you could apply to properties. This is what statically checks and prevents you from modifying said property.
There's also `as const` which is used to cast all properties of an object as readonly. I believe it's also used to define literal types.
In JS, there's also Object.freeze() which prevents modification of an object's properties.
All in all, a different language. Don't forget that JS is an embedded language and can't do anything practical on its own. Its core and implementation resides in C++ (V8 in Chromium based browsers for ex.) TS is just a static analyzer on top.

If I have an idea for a program, or a basic app I can do all of it in Python test it maybe even stick with just that if it's good enough.

Pin on a pointer type is a promise that you can depend on what's in a pointer staying valid as long as the pointer is valid. Unpin on a pointee means that it doesn't need that promise, and that you can move it out anyway.
Pin is needed for generic/library code to be able to trust that it can keep interior pointers around, in particular for async code to keep references to other stack variables around at an await point. You can commonly provide it either by pinning an existing value to the stack with pin!, or moving it to the heap with Box::pin(), both of which prevent you from moving the value out.
Unpin means a type doesn't need to be pinned, or equivalently, that you can safely remove the pin. It can be used either to assert than a type doesn't require pinning, or to allow generic code to let callers have a nicer API if they know it doesn't matter for some type, as methods can be conditionally available on a generic parameter implementing a trait.
A confusing detail is that pinned pointers are themselves a good way to get an Unpin from a value that isn't already Unpin: this is because if it's already pinned, you don't need to work about adding any more pinning.
LUA is incredibly useful if you ever need to embed a scripting language into an application. And there are a lot more reasons to do this than the average lay person might suspect.
I believe that since all of Valve's games, support modding and Lua is the main scripting language used for them. So I can assume that you can integrate Lua modding in your game easier than with other languages.
C++ standard library is super ugly for two main reasons: it must only create identifiers defined by the standard or with the reserved double underscore or underscore Capital patterns; and it often wants to share behavior without hitting the C++ issue where each base class must have a separate address by using recursive template definitions and other metaprogramming techniques.
They don't actually write the code with the underscores, btw, it's run through an uglifier script.
BRAZIL MENTIONED 🥳 Brazil ♥ ThePrimeagen
There are some "things you can do in JS" that TS by default won't let you do even though it is actually safe. But thats more that ALL JS runtimes have certain standard library things behave one way but the spec is more strict. And TS has those all typed to the spec.
Isn't there a declaration you need to make to put Typescript in strict mode?
The rust compilation complete in the end was *chef kiss*
I'm using C++ and LUA daily since many years, so they're both S-Tier in my programming languages tiers list (for completely different reasons).
No real opinion on other languages since I rarely use them, ofc there is what I call the "classic webdev duo" (PHP and JS) I use sometime.
Python is also great to make quick program and there is a big community around.
PHP! I built my app with PHP. Great for new developers.
I learned from one UA-camr that to read C++ consts if it's in the beginning (which means there's nothing to its left to make it const) then it makes the first thing to its right a constant, but wherever else you put it it makes the thing to its left constant
We need to just stop using Javascript for anything other than front-end scripting. Y'know, the thing it was designed for. It's easy to say JS is a trash language when you use it in a domain it isn't meant to be used.
It's like trying to use Java on something that isn't a blueray player, or Python on a computer. When you use a language not how it is designed to be used, it'll seem like trash.
well even then, C is the best scripting language
@@anon8510 C is a scripting language to avoid writing assembly, so obv all software should be written in it, as there are no bounds to what you can do with it.

It's trash for frontend scripting too.
Appreciate the python dunk though
@@anon8510 I know, it was a joke :)
@@anon8510 warning: text wall and hot take
scripting is the act of writting short, quick and dirty programs "scripts" or parts of programs, which can be either to alter the behaviour of a preexisting system without recompiling most of it, or for accomplishing tasks as they come up
C shines most in that kind of environment where you don't necessarily want a fancy language complaining about out-of-bounds array accesses or reading uninitialized memory when you either know why you're doing it or don't care about the possible consequences
and with how simple the language is, you want even notice recompiling most script-scope shared objects / mini-programs
try writing a simple single-use command-line program with zero attention given to either security, performance, error tolerance, generalisability, maintainability or readability and you'll find C is the easiest answer in most cases, though sometimes beat by Perl or Python
want to embed a scripting language in an app you're making? you could add a dependency on an interpreter and do complex maneuvers to respect your guest language's assumptions, or you could just dlopen(3) a shared object, probably written in C, that couldn't care less what you do with its memory (not mentioning that if you provide a C API, adapters for many other mainstream languages are trivial to implement (if it isn't automated))
"but manual memory management" - just leak / use an arena
"but no generics" - you won't need them for a script, but if you really must then void * and macros are things
"but mandatory types" - C23 has type inference
"but no data structures" - arrays are all you need
"but integers are finite" - like you're gonna overflow a long long

i want someone who thinks like Go/C bare min but you can move the world with it.
Nice of you to give the dude like 200 subs, well done
He is at 14k subs now
For those curious, std::pin simply means the memory address is locked, while std::unpin will allow it to change memory locations. For example, if you want rearrange the data to sit in memory better, you can pin specific values to an address and know that they will always be in that location. Not far from describing pinning a note to a cork board.
Now, from what I understand of this, it sounds like a way to memory map. I would think this would be more bare metal, but I don't know what it could be used for outside of memory mapping.
I avoided go for like 5 years and finally tried it this year. It is so easy! It’s easy to compile and is no where near as buggy as JS
I don't really love PHP that much, despite I have to use it nearly every day. But E tier is definitely inappropriate
The rust take is pretty accurate... you know which one I mean.
"Features are for the weaks", man i got you. Don't be afraid to use pointers if necessary. Your responsibility as a programmer is to write good software. Prioritizing safety and an easier path can make you a weaker programmer
ELixir Mentioned Letss goo
Take a drink every time ThePrimeagen appears on the video ThePrimeagen is reacting to.
My first language was basic and yes, it is a special language.
For rust, I think the pinning is the making a object constant without declaring it as such when its created or its value defined, so that another async op needing it, can set it to be a static object, before returning and it can get unpinned
"C# is better than Java" is a ringing endorsement from Primeagen! 😁
Along with a shit ton of bias :)

“Php is only useful for the web and even that is easily done with other languages” is one hell of a take lol
You could do web in other languages/stacks, and have an objectively worse time, all the time. PHP Lives and Dies by the Request/Response life cycle which is 👌 perfect for delivering web pages. You know what else is fantastic as a Request/Response? CLI tools. Yes. Absolutely. PHP is so shocking excellent at making CLI tools I’ve stopped using python and C++ in favour of it.
I wouldn’t advocate for an S tier or anything but it absolutely does not belong in E lol it’s way too useful for that
I have done that a bunch. It is a nice middle ground between bash and c.
Many years ago I wrote quite a lot of CLI tools in PHP…
Why?
I didn’t want to add any additional software onto the server, and PHP can handle everything I needed it to do.
It does fantastic at CLI tools, just like a web page, feed it options (query params) and let it generate a response.

Ngl, I like Python. It does what I need it to.. most of the time.
I piddled around in BASIC as a kid, and in high school I took a class where we did Pascal on greenscreen dumb terminals. But my first nontrivial programming language was C. I remember the day I learned about pointers. I had a massive headache. Then I added C++ to my toolkit. I liked that wrapping stuff in objects made it easier to pass larger payloads of information around. I did some Java in college for EE (along with some more C, C++, and assembly), and I've dabbled in Python, JavaScript, PHP, MATLAB, and some other esoteric stuff (LabVIEW, anybody?). But when I need to actually get stuff done, I always go back to C or C++.
My younger brother got a CS degree and learned entirely in C#. Then he got a job and saw "malloc" in code he was maintaining. He didn't even know what it was.
Very cool!!! Got tons of insights, subscribed to you guys!
My first language was C++. It does not have a special place in my heart.
19:17 you're supposed to read it from right to left!
const T* const
^ a const pointer
const T* const
^ to a const value
But a better way to write const in c++ is "T const* const" (or for example "T const&")
It makes much more sense, because you can literally read it (from right to left) as "const pointer to a const T"
Haram-tier is pretty funny.
I mean, there is code that will make typescript complain but is allowed in javascript, such as this:
const a = 0;
a = "0";
It will still "transpile" the code to javascript, but it will also tell the user that there is an error. Not sure if you can call it a superset if it doesn't think it's valid.

Java changed my life 25 years ago. Rescued me from Window's client server hell and cured me of my Smalltalk fantasies. It has had the greatest impact on the software engineering profession than anything else in history.
Can you elaborate?
@@keldencowan At the time there were three vendors of Smalltalk. The language was awesome. The IDEs they provided were awesome. But the final product was mostly unusable. Connecting to various databases was expensive or not possible. The real problem was they couldn't generate an executable application file with a reasonable footprint. Java came along and gave as an OO language that could do everything for everyone. In those days we made desktop client server apps using PowerBuilder, Delphi(me), and a little later C++ with Visual Studio. They only worked on Windows and required sophisticated UI programming and were a hassle to deploy to users and get them working for everybody.
For use as well. We were in hell with Windows client back in the day. Moved to Java and we were happy. Still use it now. We're doing Data Engineering with Databricks all running on the JVM. Super cool stuff.

Templates in c++ are compile time executed and therefore pretty ugly to debug. But they are lightning fast. Together with the STL they provide a sweet spot between performance and usability. Try to outperform the STL in any task. It is very hard and for most impossible.
If you're not extremely careful, they blow up in code space which thrashes your instruction cache. But in the hands of an artist, you can achieve performance not far below hand-coded assembly language.

You should make a programming tier list with esoteric programming languages
I don't get the love for C over C++, you can program in C++ exactly like C and benefit from stronger type safety and, if you choose, make use of built in classes, references, templates etc.
There is something nice about the simplicity of C, even if it is not a very practical language.

Try to manipulate any sort of nontrivial series summation with 1-indexing vs 0-indexing, and then tell me which one is easiest. Or try to index into an n-dimensional array. Yes, people in the 1600s didn't know better. That's no excuse for making the wrong choice in the 21st century.

The c++'s std::variant definition mess showed in the video is actually not that horrible (pretty much everything else about std::variant is, though). Most of the typing is only namespace resolution. Then, the goal is to enable or disable the usual copy/move constructors/assignment operators based on the properties of the types in the variant. It makes the top level of std::variant trivial as all operators can now be defaulted. Private inheritance is a very usefull metaprogramming feature to conditionnally define member functions (and sometimes variables) based on template parameters properties.
