#7 Mozilla Developer Network

The Mozilla Developer Network is the official Mozilla Foundation website for development documentation of web standards and Mozilla projects. It is a resource-rich collection of documents about web development, made for anyone, from expert programmers to students just starting out. MDN is a wiki, meaning anyone can edit its pages with corrections and updates.

The initial content for the website was provided by DevEdge, for which the Mozilla Foundation was granted a license by AOL. Significant effort has been made to migrate content from mozilla.org. Many pages on mozilla.org now redirect to MDN. The site now contains a mix of content migrated from DevEdge and mozilla.org, as well as original and more up-to-date content. Documentation was also migrated from XULPlanet.com. MDN is a wiki, so anyone can edit its pages with corrections and updates.
