In this tutorial we continue our discussion on Arrays. We demonstrate the built in JavaScript function that converts array content to strings. Using the toString() method we can convert an Array to a comma separated list. We also demonstrate using the join method inside of JavaScript. We demonstrate how to replace an item in the Array based on the index number. We also look at ending a value to the end of an array by using the length property. We also look at the splice methods in an Array and that method allows us to add elements, remove elements into an array location.
