587d7daa367417b2b2512b6c	Combine an Array into a String Using the join Method	1

Description

The join 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:

var arr = ["Hello", "World"];
var str = arr.join(" ");
// Sets str to "Hello World"

Instructions

Use the join method (among others) inside the sentensify function to make a sentence from the words in the string str. 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 replace method.

Tests

tests:
  - text: Your code should use the <code>join</code> method.
    testString: assert(code.match(/\.join/g), 'Your code should use the <code>join</code> method.');
  - text: Your code should not use the <code>replace</code> method.
    testString: assert(!code.match(/\.replace/g), 'Your code should not use the <code>replace</code> method.');
  - text: <code>sentensify("May-the-force-be-with-you")</code> should return a string.
    testString: assert(typeof sentensify("May-the-force-be-with-you") === "string", '<code>sentensify("May-the-force-be-with-you")</code> should return a string.');
  - text: <code>sentensify("May-the-force-be-with-you")</code> should return <code>"May the force be with you"</code>.
    testString: assert(sentensify("May-the-force-be-with-you") === "May the force be with you", '<code>sentensify("May-the-force-be-with-you")</code> should return <code>"May the force be with you"</code>.');
  - text: <code>sentensify("The.force.is.strong.with.this.one")</code> should return <code>"The force is strong with this one"</code>.
    testString: assert(sentensify("The.force.is.strong.with.this.one") === "The force is strong with this one", '<code>sentensify("The.force.is.strong.with.this.one")</code> should return <code>"The force is strong with this one"</code>.');
  - text: <code>sentensify("There,has,been,an,awakening")</code> should return <code>"There has been an awakening"</code>.
    testString: assert(sentensify("There,has,been,an,awakening") === "There has been an awakening", '<code>sentensify("There,has,been,an,awakening")</code> should return <code>"There has been an awakening"</code>.');
