Course description

JavaScript is the programming language of the World Wide Web, the code that makes a Web page come alive. This course is focused on working with Constructors, Literals and Prototypes of Objects.


This course assumes that you have at least some programming experience in one or more modern programming languages. JavaScript will be particularly easy for you to learn if you have experience with any C-style languages—including Java, C#, C++, or Visual Basic .NET would be helpful—but this is not required. The focus here is not on programming concepts but on the structure, syntax, and use of the JavaScript language.
