In 2017, more than 8,000 developers contributed to 80,000 pages of content on the Mozilla Developer Network. Mozilla also teamed with Microsoft, Google, and other industry leaders to greatly expand the scope of MDN web docs. It’s a huge collaboration and one that we all hope will make the web a better place for developers and consumers alike.

The Mozilla Developer Network (MDN) is one of the most popular resources for developers on the Web. Designed by developers for developers, MDN helps support Mozilla’s mission to promote openness and innovation on the Web.
