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],
            


        

Answer 1

Here is an ES6 solution:

myArray.some(
    r => r.length == itemTrue.length &&
         r.every((value, index) => itemTrue[index] == value)
);

Check the JSFiddle.

Take a look at arrow functions and the methods some and every of the Array object.
