How to print a space between each word in an array

Question

I remember seeing a function on w3school where you can print out all the words of an array and add a space between them, But no matter how much I google I can't find it.

Example of how it could look:

    function printWords() {
      var array = ["Car", "Bus", "Motorcykle"];
      print(array.addSpaces());
    }

Answer 1

Use Array.prototype.join(). You can specify a character to put between the values, in your case:

array.join(' ');
