indexOf array in array?

Question

I am most likely overlooking something something pretty basic here, but I have a really hard time figuring out why I get the following behaviour, when looking for a specific array in another array:

myArray.push(["Name", 1, 2]);
myArray.indexOf(["Name", 1, 2]);

Returns -1.. Why can't I find the array that I just pushed?

Because each time you use […] you create a new array. indexOf compares references. — Sebastian Simon

That makes sense. Can you give me heads up on how to achieve the behaviour im looking for? — user2806026

This seems to be a duplicated question. Here is the link to a quit similar problem: stackoverflow.com/questions/24943200/… — Bent Auweiler

Try this:

var myArray = [];
var anotherArray = ["Name", 1, 2];

myArray.push(anotherArray);
myArray.indexOf(anotherArray);  // returns 0

Try something like this:

var checkArray = ["Name", 1, 2]
var myArray = [];

myArray.push(checkArray);
myArray.indexOf(checkArray);
