Description

With JavaScript array variables, we can store several pieces of data in one place. You start an array declaration with an opening square bracket, end it with a closing square bracket, and put a comma between each entry, like this: var sandwich = ["peanut butter", "jelly", "bread"].

Instructions

Modify the new array myArray so that it contains both a string and a number (in that order). Hint
Refer to the example code in the text editor if you get stuck.

Tests

tests:
  - text: <code>myArray</code> should be an <code>array</code>.
    testString: assert(typeof myArray == 'object');
  - text: The first item in <code>myArray</code> should be a <code>string</code>.
    testString: assert(typeof myArray[0] !== 'undefined' && typeof myArray[0] == 'string');
  - text: The second item in <code>myArray</code> should be a <code>number</code>.
    testString: assert(typeof myArray[1] !== 'undefined' && typeof myArray[1] == 'number');

Challenge Seed

// Example
var ourArray = ["John", 23];

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

After Test

(function(z){return z;})(myArray);

Solution

var myArray = ["The Answer", 42];
