In order to learn programming, many people bought a bunch of related books, and participated in a lot of online courses, and even spent hundreds of yuan to buy a set of teaching CD-ROM, in the end will not be programmed, very worthless. Codecademy is a newly launched web site that provides users with a new way to learn about programming. It is a web-based interactive programming tutorial that helps users understand some of the basics of
