This video breaking a lot of noob/experience myths. Thankyou. please correct me if my statement is wrong w.r.t closure: A function which wrap another function with its lexical scope and bundle together forms closure.
I really brushed up lot of things. Yes I completely agree that the information you are providing is not at all found on any blog.. I'm excited to grab the knowledge from you by watching all the videos.. Few doubts I have 😅 1. Everytime there is one question they ask me about closures is, Can you give me a real world example or can you explain me why closure is needed. I would like to know the answer from you. 2. How do you evaluate the client side code when a user is opening external urls/multiple sites from our application. How do you validate that person on that external urls page as Auth token or client code is already been used in our application 3. Advantages of arrow functions apart from syntax 4. Disadvantages of Virtual DOM 5. Why don't we update props ? 6. How do we destroy data ? (let's say I don't want any data)

@@careerwithvasanth 📌 First example2 FEC(Function Execution Context will be created) 📌 Then this function will go into two phases of code execution i.e. 1. memory allocation and 2. code execution 📌 In the first phase, JS tries to register this self-invoking function but it sees it and executes it immediately. 📌 So, till now code execution phase has not yet started, so setTimeout() is also not yet executed. 📌 This is the reason why setTimeout() is not able to stop the execution of that function.
I think the easy answer is because the first argument of setTimeout is supposed to be a reference to a function and not the function call itself. For ex. Its the same reason why onClick={myFunction()} executes immediately on render vs onClick={()=>myFunction()} only executes on click. SetTimeout is a promise that takes a callback function that is placed onto the callback queue. So bascially you're not giving the callback queue a refrence to that function rather your just calling it immediately
Thank you so much Sir ... A lot of doubts were covered in this video. And honestly I didn't find it to be a long one as I was able to learn a lot .. Thanks again ☺️

After searching for a solution, it looks like IIFE inside the setTimeout prevents the delay. It ultimately makes it run immediately and turns the delay useless (it won't ever get called with it). Let me know if this is correct

@@careerwithvasanth it's not waiting for function to invoke, executing at line 5 only, and it would return undefined as setTimeout still in macro Queue. But I also read that setTimeout executes asynchronously even with an IIFE. So I didn't able to figure out after returning undefined from IIFE, how it showing answer 0 1 2 🤔

Replying to 34:59 SetTimeout actually schedules the return value not the execution of the function which is why we get 0,1,2 in the output.
The argument of setTimeout should be a reference to a function (function expression) and not the return value

Hi , In ES6 they introduced class system in js then how hoisting is happening there in case of functions

Nothing as such Santhosh, both can pay high. Just you need to be master that's it.

Sir Sound quality doesn't seems good.
Shreyash, yeah working on better voice quality !!
But arrow function are not hoisted
Yes they are not hoisted !
Excellent Video.
The declarations appear to be hoisted.... instead of being actually hoisted... Ok
Ok, but why is this question important? It is a simple info. Even it were actually hoisted (it doesn't), would it make any difference?
It just explains the depth of understanding !! is it important , that varies depending upon interviewers expertise.
12:47 brother confused his channel name 😂
I never find such a video on any sources thank s a lot for the everything
Thank you !!
Sir you speak very fast
Some understand what you are saying and some don't understand so what are you saying
Input taken and will work on it to improve.Thank you
Explaining in Hindi should be more better for the audience to be friendly with u .....as we are not small childrens
