MDN is committed to providing modern web development documentation to over a million developers daily. Due to the rapidly-evolving nature of the web platform, and the tremendous innovation happening in the browser space, developers have a hard time keeping up with the constantly evolving landscape and they lack a common language to talk about the features that are generally available for use on the web. To address these issues, Mozilla has engaged in a two-fold approach.
First, we have actively participated in the WebDX Community Group, collaborating with organizations like Google, Apple, W3C and others to develop the Web Platform Feature Set: a common language to describe platform features.
Second, through MDN, Mozilla is now the first to use this dataset to offer a transparent, unified view of stable, well-supported features and display the Baseline support for the web platform.
