## Description
|
||
|
|
<section id='description'>
|
||
|
|
The <code>join</code> method is used to join the elements of an array together to create a string. It takes an argument for the delimiter that is used to separate the array elements in the string.
|
||
|
|
Here's an example:
|
||
|
|
<blockquote>var arr = ["Hello", "World"];<br>var str = arr.join(" ");<br>// Sets str to "Hello World"</blockquote>

## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Use the <code>join</code> method (among others) inside the <code>sentensify</code> function to make a sentence from the words in the string <code>str</code>. The function should return a string. For example, "I-like-Star-Wars" would be converted to "I like Star Wars". For this challenge, do not use the <code>replace</code> method.
