Variable Scope in JavaScript

The "variable hoisting" is something new for me. Thanks for the awesome explanation!

Yeah, it's one of those things that you learn the hard way when you are scratching your head over why your code isn't working haha.

omg, awesome video

thank you kirupa

I was just starting to drift from the "variables at the top" best practice because I didn't really understand hoisting. Now I understand it and why the variables at the top thing is a best practice. Thanks Kirupa. Glad to see you're making high quality tutorials (I used to be on your forums back when @pasql was still DarkMotion -- several years ago). Happy I stumbled upon this channel and your site again!

You are really good. You deserve higher views.

Merci :)

Looks like you are reading from the monitor but its good tutorial

Your presentation is awesome and slides also are awesome

var days=['jan','feb','mar']
for(var i=0;i<days.length;i++)
{
const ele=days[i];/*how it is executed I am confused about constant bcoZ const cannot be reassigned */
console.log(ele);
}
thank u sir

all the explication is fine but how do I expose the variable after being use to the global holding the new value ?

I should have never watched this while stoned.

Very nice explanation
