title: Split a String into an Array Using the split Method
|

## Description
|
|
<section id='description'>
|
|
The <code>split</code> method splits a string into an array of strings. It takes an argument for the delimiter, which can be a character to use to break up the string or a regular expression. For example, if the delimiter is a space, you get an array of words, and if the delimiter is an empty string, you get an array of each character in the string.
|
|
Here are two examples that split one string by spaces, then another by digits using a regular expression:
|
|
|
|
```js
|
|
var str = "Hello World";
|
|
var bySpace = str.split(" ");
|
|
// Sets bySpace to ["Hello", "World"]
|
|
|
|
var otherString = "How9are7you2today";
|
|
var byDigits = otherString.split(/\d/);
|
|
// Sets byDigits to ["How", "are", "you", "today"]
|
|
```
|
|
|
|
Since strings are immutable, the <code>split</code> method makes it easier to work with them.

## Instructions
|
|
<section id='instructions'>
|
|
Use the <code>split</code> method inside the <code>splitify</code> function to split <code>str</code> into an array of words. The function should return the array. Note that the words are not always separated by spaces, and the array should not contain punctuation.

tests:
|
|
- text: Your code should use the <code>split</code> method.
|
|
testString: assert(code.match(/\.split/g), 'Your code should use the <code>split</code> method.');
|
|
- text: <code>splitify("Hello World,I-am code")</code> should return <code>["Hello", "World", "I", "am", "code"]</code>.
|
|
testString: assert(JSON.stringify(splitify("Hello World,I-am code")) === JSON.stringify(["Hello", "World", "I", "am", "code"]), '<code>splitify("Hello World,I-am code")</code> should return <code>["Hello", "World", "I", "am", "code"]</code>.');
|
|
- text: <code>splitify("Earth-is-our home")</code> should return <code>["Earth", "is", "our", "home"]</code>.
|
|
testString: assert(JSON.stringify(splitify("Earth-is-our home")) === JSON.stringify(["Earth", "is", "our", "home"]), '<code>splitify("Earth-is-our home")</code> should return <code>["Earth", "is", "our", "home"]</code>.');
|
|
- text: <code>splitify("This.is.a-sentence")</code> should return <code>["This", "is", "a", "sentence"]</code>.
|
|
testString: assert(JSON.stringify(splitify("This.is.a-sentence")) === JSON.stringify(["This", "is", "a", "sentence"]), '<code>splitify("This.is.a-sentence")</code> should return <code>["This", "is", "a", "sentence"]</code>.');
