--- id: 587d7daa367417b2b2512b6c title: Combine an Array into a String Using the join Method challengeType: 1 forumTopicId: 18221 dashedName: combine-an-array-into-a-string-using-the-join-method --- # --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: ```js 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. ```js assert(code.match(/\.join/g)); ``` Your code should not use the `replace` method. ```js assert(!code.match(/\.?[\s\S]*?replace/g)); ``` `sentensify("May-the-force-be-with-you")` should return a string. ```js 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"`. ```js 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"`. ```js 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"`. ```js assert( sentensify('There,has,been,an,awakening') === 'There has been an awakening' ); ``` # --seed-- ## --seed-contents-- ```js function sentensify(str) { // Only change code below this line // Only change code above this line } sentensify("May-the-force-be-with-you"); ``` # --solutions-- ```js function sentensify(str) { // Only change code below this line return str.split(/\W/).join(' '); // Only change code above this line } ```
