Closures in JS | Namaste JavaScript Episode 10

I didn’t understand one thing like while calling the z(); how 7 is printed can any one please explain it to me, n how z is called though it’s just a variable ?

in the closures example how variable z becomes function in 11 line? can anyone explain please?

bro just roasting all other language like they are nothing

thanks sir ,I am falling with love in javascript

Thank you for sharing

Thank you so much bro!!! I've watching so many videos and reading articles and this is the one that sticks!! I can't believe it was just that simple!

akahay saini is the king of javascript

Forget Netflix. Binge-watching this masterpiece!

Interviewer: what is function?
me : Function is so beautiful so elegant just looking like WOW!!!

🎉

Closure is function bundled with lexical scope. Thank you saini sir

This is due to shadowing...... x from 7 to 100

very informative

Great work Akshay

bro u nailed it

today ending music was of ritviz

Revision Points :
1. A closure is a function that comes bundled with its surrounding variables (lexical scope).
2. Even when we return a function, it still remembers the environment it was created in, so it can access those variables.
3. If we write `return function x() { ... }`, we are returning the function itself, not its value. The function needs to be called to return a value.
4. The returned function is a reference, so any changes made to variables inside it will affect the original variables.

if anyone of the viewers is making note can you please share it with us !!!

Who drinks green tea ! Lol i laughed so hard at this. You make learning javascript so much fun akshay !

Thanks

closure: Closure is a function that remembers and has access to the variables of it's outer scope even after outer function has finished executing.

for e.g -

function a(){
let c = 10;
function b(){
console.log(c);
}
return b;
}

let z = a();
z();

In above example the execution context of function "a" is long gone yet this function "b" remembers the values of variable c.

What extension you used in vs code

great

Oh my godd....I fell in love with his explanations of the closure concept. The way he explains the clouse concept was top notch😍

plot twist: tomorrow you have js interview

Not clear explanation

video is useful

hindi mein samjhao sir

wtf is going on...hahaha

Can you explain y im getting 3 and undefined at output for this code function x(){
var a=3;
function y(){
console.log(a);
}
y();
}
let z=x();
console.log(z);
my doubt is i wrote y() in x() function so when i access x() through let Z why its showing undefined ? it return 3 for the first time why undefined for 2nd time for not mentioning return statement.

I want to say we love you man! Thank you for all the efforts and time you devote to making awesome videos like this.
