Hoisting in JavaScript (variables & functions) | Namaste JavaScript Ep. 3

very exited

No one teaches this

awesome video brother you are just too good in explaining

I just like your energy level.... thank you for all ur effort

I have seen a lot of you tube videos for this and honestly no one has explained like you❤ ..it was a great great explanation...and now after learning from you I'm actually feeling like a pro😂😅

extremely excited man, loving the tutorial so far.

Sir please explain currying in js

Best teacher ever ! sending love from pakistan

Which IDE you are using?

🤩🤩

same example with let and const behave like ? plz answer this

Thanx Akshay Bhai

awesome

great bro

Video was so interesting❤

what will happen in case we use let or const?

Thanks for explaining Hoisting clearly, best video on hoisting

Sir so what will be the definition of hoisting when explained in terms of execution context and call stack?

Hoisting does not work the same way for function expressions and variables declared with let and const.

please can you stop moving your hand that is making this course uncomfortable

thx bro

You need subtitles man

Thnks for the video, could you please explain how could you debug the code line by line in chrome browser?

stupid language honestly

if (false) {
var n = 0;
}
else {
let n = 9;
}
console.log(n)

why doesn't the code throw an error but the one below does

if (false) {
var n = 0;
}
let n = 9;
console.log(n)

THANKSSSSS 😍😍

yes i feel excited

Explanation was good , I liked it '

what shortcut did you use to start the debugger in chrome?

Bro, You made me fall in love with JavaScript! ❣❣

Wow man. This series is incredible. Each video has its own beauty of simplicity. Thank you very much!!

hi Akshay, i'm new to js and i dont know about its synatx or anything about js i dont know how to start the js from vs code to console in chrome pls guide me some steps.. thanks for your support!!

Awesome video

💯

It feels so good learning what hoisting is, before watching this video when i hear the word hoisting i always think of something more difficult to learn, but with your explanation it becmes more easy.

Whenever javascript execution occurs there involves two steps .1) Memory creation 2) execution phase ... memory creation phase and execution phase both ocuurrs in call stack...one thing also ...at creation time the variable which is made up of using var keyword will stored value as undefined at the time of creation phase while for normal function value takes it as a whole ....thats why we can call function anywhere in the global execution contrext .

Note: for arrow function and function expression there is no. Hoisting....we can't hoisted bcz they are also treated as variable ...

gone though many javascript courses, videos, lectures, but unsatisfied with their explainations finally found the best chanel for learning javascript

Very Exicing .. Thanks

excellent explanation

Also, If you declare a JavaScript file with 'use strict'; this will mean that hoisting using var will throw a ReferenceError.

let and const variables are hoisted but not initialized? is it correct..

Thank you sir for giving valuable information about js browser, and your explanation is superb 😊

nothing fancy, KISS - keep it super simple.
All declarations (var, let, const, function, arrow Fn, class) are "hoisted" in JavaScript. This means that hoisting is the mechanism by which we are able to access the variables before their declaration.

The difference between var/function/function* declarations and let/const/class declara­tions is the initialisation.

The former are initialised with undefined or the (generator) function right when the binding is created at the top of the scope. The lexically declared variables however stay uninitialised.

This means that a ReferenceError exception is thrown when you try to access it. It will only get initialised when the let/const/class statement is evaluated, everything before (above) that is called the temporal dead zone.

great content bhaiya

GOD

awww what a big magic
