587d7daa367417b2b2512b6c	Combine an Array into a String Using the join Method	1	18221

--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.

--hints--

Your code should use the join method.

assert(code.match(/\.join/g));

Your code should not use the replace method.

assert(!code.match(/\.?[\s\S]*?replace/g));

sentensify("May-the-force-be-with-you") should return a string.

assert(typeof sentensify('May-the-force-be-with-you') === 'string');

sentensify("May-the-force-be-with-you") should return "May the force be with you".

assert(sentensify('May-the-force-be-with-you') === 'May the force be with you');

sentensify("The.force.is.strong.with.this.one") should return "The force is strong with this one".

assert(
  sentensify('The.force.is.strong.with.this.one') ===
    'The force is strong with this one'
);

sentensify("There,has,been,an,awakening") should return "There has been an awakening".

assert(
  sentensify('There,has,been,an,awakening') === 'There has been an awakening'
);

--seed--

--seed-contents--

function sentensify(str) {
  // Only change code below this line


  // Only change code above this line
}
sentensify("May-the-force-be-with-you");

--solutions--

function sentensify(str) {
  // Only change code below this line
  return str.split(/\W/).join(' ');
  // Only change code above this line
}
