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"].
myArray so that it contains both a string and a number (in that order).
HintmyArray should be an array.
testString: 'assert(typeof myArray == "object", "myArray should be an array.");'
- text: The first item in myArray should be a string.
testString: 'assert(typeof myArray[0] !== "undefined" && typeof myArray[0] == "string", "The first item in myArray should be a string.");'
- text: The second item in myArray should be a number.
testString: 'assert(typeof myArray[1] !== "undefined" && typeof myArray[1] == "number", "The second item in myArray should be a number.");'
```
