Understand scope & hoisting in JavaScript in the most Effective and Funniest way

You must have a crystal clear idea about scope to become a better javascript developer. Besides, you cant be an expert if you dont know hoisting.

This video makes you smart enough to explain hoisting and scope to your grandmother. Thats my promise.

I've been watching your videos for a while and now I feel like a javascript ninja that can kick a PHP programmer ass with my awesome js code.

Surely, you meant *Kanye, * not Kayne. And I didn't realize Kim was so old already. (Or was that a Freudian slip? Lol)

nice analogous tutorial :).Must say you have interesting sense of humour

[tameshwarnirmalkartest]

function x(){
function a(){
console.log(b);
}
a();
var b = 7;
}

x(); // Why is giving undefined as you said function hoisted top of it.

[tameshwarnirmalkartest]

var a =10;

function x(){
console.log(a);
var a = 20;
}

x(); // Again undefined why?

did you also just do closures in this video?

[tameshwarnirmalkartest]

function x(){
console.log(a);
var a = 10;

}
x(); again this is coming undefined why?

Despite the fact that you have the second worst eng accent in the universe that was a super useful and nice presentation. I just wondered why hoisting was necessary??? is it just the fact that ECMA script didn't want to show an error message on that particular fact like other languages? I guess hoisting is not a name given by the ECMA Int.
