| bd7993c9c69feddfaeb8bdef | Store Multiple Values in one Variable using JavaScript Arrays | 1 |
Description
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
myArray so that it contains both a string and a number (in that order).
HintRefer 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', '<code>myArray</code> should be an <code>array</code>.');
- text: The first item in <code>myArray</code> should be a <code>string</code>.
testString: assert(typeof myArray[0] !== 'undefined' && typeof myArray[0] == 'string', 'The first item in <code>myArray</code> should be a <code>string</code>.');
- text: The second item in <code>myArray</code> should be a <code>number</code>.
testString: assert(typeof myArray[1] !== 'undefined' && typeof myArray[1] == 'number', 'The second item in <code>myArray</code> should be a <code>number</code>.');
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];
