- ► Full Angular Interview Prep Course - monsterlessons-academy.com/co...
This course is great preparation for any Angular programming interviews that you may have coming up. Programming interviews need a lot amount of knowledge, but the best way to prepare for interviews is a lot of practice! In this course you will complete 56 Angular interview questions that come from real Angular interviews. There are no excersises that nobody asks here. In every question we will get a task first, then you will try to solve each problem yourself, and then I will show you different solutions to each problem step-by-step for different programmer levels. We will take a deep dive into the skills, concepts, and techniques that are required to solve each problem.

This was great! Got interviews coming up and this helped a lot.
Glad to hear that!
It was very useful and I did get a job :-)
Thank you. It's great video :)

Thanks!
Thank you so much for your support! It means a lot to me.
Greate! Thank You!
Glad you liked it!
Much thanks for this video. It was very, very helpful. I will surely subscribe to your channel and watch more of your learning videos.
Welcome aboard!
Apart from a good tutorial, Your videos are also very relacsing .. A big Thanks in order, BTB which Editor and Font u r using, looks very soothing
Thank you! It's monaco font and Vim. ua-cam.com/video/YrLiugDhCuk/v-deo.html
This is not about Angular at all, it's just about typescript...
It is a first section of the course and not the whole course.
@@MonsterlessonsAcademy I don't see it grouped in a series? And the title is misleading?
@@Asaloy At the beginning I'm talking that this is a part of the paid course. The link is in the description.

Angular interview questions, proceeds to talk for 45 minutes about typescript basics
This is the first section of the full course. As Angular uses heavily Typescript and RxJS you can't know Angular on a good level without these 2 things
now you can simply add quesiton mark to fix the getItem fn error
```
const getItem = (item: number | undefined) => {
return item?.toString();
};
```
Thenks a lot.Usefull content
Glad you liked it
Amazing video ❤
Thank you!
Your Video is always helpful for me Thanks 🙏
Glad to hear that!
hi, please tell me what kind of font you are using in the editor
It's monaco
You are the best teacher.
Please create a video about postgres from 0 to advanced
Thank you for the idea!
13:30 oh no, this is not quite right either, because you wouldn't be able to convert number 0 to string in this scenario.
You are totally right. We must check for undefined
Could you please how you set-up your vim =) like course?
I can but as my Vim videos are not highly popular I don't want to spend time on making the whole course which won't be popular.
What time does it take to finish the whole course? How many hours are there?
5:49 hours.
Please bring this for React.Js also.
Will do that!
If an interviewer asks me why TypeScript enams are so good im outta there.
Also you are giving bad advice with the 'as' keyword for explicit type assertion. If you do this in an interview all it tells them is you don't understand how TypeScript works. Instead using type narrowing or type guards, which actually make the code typesafe, not just telling the typescript checker that "i know better what type this is 4head".
Coincidentally, just use a damn union type of string literals instead of enums. You get all the benefits, and it still is a string. And you can use type narrowing.
There are cases where type guards won't help you like as HTMLInputElement for example.
String union is just a type there is no value inside. Enum has both.
Bait title, wasted 50 minutes on TS basics.
This is a first section of my full course Angular interview questions.
lol, 13:55 is not best possible solution, actially it is not a solution, because your function return wrong result if you pass 0
You are totally correct!
This course is not about angular)))
The first 2 sections are about Typescript and RxJS. From my perspective you can't use Angular on a good level if you don't know them.
A bait for the paid course lol
You get 45 mins of content to understand if you like an instructor and content. I mention at the very beginning that this video is a part of the full course.
sorry dude, this video is PRETTY BAD. too many things are off.
1) typescript is not angular. there was not a single question about angular. naming the video "angular interview questions" just to get some clicks is LAME
2) i'm pretty sure that one is not the elvis operator. in other programming languages Elvis has indeed both of his eyes ( ?: ) and the operator is for something else
3) enums are NOT good. typescript itself discourages the use of enum. Matt Pocock made the point very clear a while ago. also a quick google search can give you an idea
1. It''s a first section of the course which I say at the beginning.
2. You are wrong and you could google it before writing your comment.
3. I don't care what one developer said. Lots of projects use them with success.
@@MonsterlessonsAcademy
you answers are even lamer lol
1) still wrong title. click bait. it's so easy to set a proper title that it's obvious you set it wrong on purpose
2) yes, quick search. exactly as i suggested you on point 3: first result on google is the wikipedia page, exposing again your mistake. you could have checked yourself but i guess we know already your approach: en.wikipedia.org/wiki/Elvis_operator
3) a lot of projects work fine with bad practices too. this doesnt mean they suddenly become best practices. not caring of what community and official doc say it's something that tells a lot of you.
i guess you'll reply with even lamer answers (if possible), so i probably stop here.
generally speaking, i appreciate the effort that people like you put on the sharing/teaching work. nonetheless, you should take bad feedbacks as opportunities to improve instead of trying (and failing) to justify yourself.
i'll let you have the final word on that. have a nice day and good luck with your channel
bye
Thanks!
Thank you so much for your support. It means a lot to me!
