Javascript Hoisting For Multiple Declarations Of The Same Variable

I was trying to understand JavaScript hoisting and from what I have understood, memory space is set aside for all the variable declarations before the execution of the code. I woul

Solution 1:

Your code will be read by the interpreter like below,

functiona() {
     console.log('hello');
 }
 var a;
 console.log(a);
 a = 2;

so while executing the above code, a will be referring the function initially and after that var a; line will be executed, since a is undefined there, an assigned value will not be set with undefined by means of a variable declaration. Hence that line got ignored and printing the primitive value of the function reference.

A simple example for your better understanding would be,

functionx(){  };
var x;
console.log(x); //function x(){  }
