Description

You can also nest arrays within other arrays, like this: [["Bulls", 23], ["White Sox", 45]]. 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

// Example
var ourArray = [["the universe", 42], ["everything", 101010]];

// Only change code below this line.
var myArray = [];

After Test

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

var myArray = [[1,2,3]];
