How to check if an array contains another array?

Question

I needed 2d arrays, so I made nested array since JavaScript doesn\'t allow them.

They look like that:

var myArray = [
      [1, 0],
      [1, 1],

You can't do like that .instance you have to do some thing by your own .. first you have to do a foreach from your array that you want to search and run 'compareArray' function for each item of your array .

function compareArray( arrA, arrB ){

    //check if lengths are different
    if(arrA.length !== arrB.length) return false;


    for(var i=0;i
