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
.');
```
