Why is object[key] not equal to key, if key is an object, in JavaScript?

Question

var a = new Object;
var b = new Object;
var c = new Object;

c[a] = a;
c[b] = b;

console.log(c[a] === a);

I tested the code above and get fa

Answer 1

I experimented with it a lit bit and @royhowie might be right. As you can see in this implementation I switched the order of the assignments and then c[a] == a gave a true.

var a = new Object;
var b = new Object;
var c = new Object;

//I switched the following lines of code
c[b]=b; 
c[a]=a;

console.log(c[a]===a);

Output: true
