[Solved] What is difference between hoisting var x = 3 and var x

by


var x declares the variable xbut doesn’t assign anything to it.

If you did set its value to undefined, then that would be undefined:

function x(){}
var x = undefined;
console.log(typeof x) //"undefined"

So what you made in your example is just 

var x;
function x(){}

While in my example it becomes 

var x;
function x(){}
x = undefined;
