Course JavaScript
The purpose of this course, as the name implies, is to cover the details of the JavaScript language. The reason we need this is that JavaScript is a core language for web development, and it is mostly misunderstood. There are many powerful features in JavaScript that many developers are not aware of. Also, learning the core concepts of the language will make libraries such as jQuery easy to understand. We use JavaScript on the client side of our web development to make calculations, create menus, and validate user data before the form is submitted to the server. These are few of the JavaScript features. We will be using Firefox and its tools to test and debug the JavaScript code.
