What is the MDN browser compatibility project?

Many browsers on countless devices aim to support a growing web technology stack in order to deliver a great user experience for as many people as possible. Unfortunately, finding out what works where often means extensive manual testing. Thankfully, a major open source project has seen Mozilla pulling together this information into compatibility tables.

In 2017, the MDN community started to migrate the compatibility information currently stored on thousands of wiki pages to a machine-readable JSON format in a GitHub repository. Having the data available in a structured form enables tools to integrate this information and flag compatibility issues at the point you’re writing code.
