This is also called a multi-dimensional array.

Instructions

Create a nested array called myArray.

Tests

tests:
  - text: <code>myArray</code> should have at least one array nested within another array.
    testString: assert(Array.isArray(myArray) && myArray.some(Array.isArray));

Challenge Seed

var myArray = [];

After Test

if(typeof myArray !== "undefined"){(function(){return myArray;})();}
