About This Class

JavaScript is used on almost every Website for tasks such as form validation, building games, and AJAX requests. But if you’re just getting started as a developer you might not know what all of that really means.

In this class we’ll look at a variety of use cases in order to discern why a developer may have chosen to use JavaScript. We’ll take this a step further by reading through (and writing) some basic JavaScript code so that we can see it in action.
