Why [] == [] is false in JavaScript?

Question

I am working on a part of the code where I have an array which looks like [[data]]. The data is rendered on the server side through the Django temp

Answer 1

Javascript is like Java in that the == operator compares the values of primitive types, but the references of objects. You're creating two arrays, and the == operator is telling you that they do not point to the same exact object in memory:

var b = new Array( 1, 2, 3 );
var c = new Array( 1, 2, 3 );

console.log(b == c); // Prints false.
console.log(b == b); // Prints true.
console.log(b === c); // Prints false.

b = c;

console.log(b == c); // Now prints true.

You have to do a deep comparison by hand if you want to compare the values of the objects.
