Answer 1

you can use this

{
var a=10;
var b=10;

if(a===b){
document.write("Same")
}else {
document.write("not Same")
}
}

but is it possible to compare to function.

Answer 4

I do not think he wants to compare the value of the variables within the functions.

And of course you can compare two functions. But for this you would have to modify your code a bit:

let myFunction = function () {
let a = 10;
console.log (a);
}

let myOtherFunction = function () {
let b = 10;
console.log (b);
}

The biggest change is that your functions are currently hosted in a variable (you can use it as you would use any function. Example: myFunction(); )

In any case, when comparing both functions, the result will always be false:

console.log (myFunction === myOtherFunction);
> false

For the result to be true, you would need something like:

let a = myFunction;
console.log (myFunction === a);
> true

var a_

function f2(){...}

a_ = f1()
b_ = f2()

..
}else {...}
