Microsoft Edge introduces great new improvements to F12 developer tools, including some of your most requested features from UserVoice. Explore new features in the DOM Explorer, Console, Debugger, Network, Performance, Memory, Emulation, and a new Experiments tool, that allows you to try out powerful new features before they're finished. The new tools are built in TypeScript, and are always running, so no reloads are required. In addition, F12 developer tools documentation is now part of the Microsoft Edge Dev site and fully available on GitHub. From this point on, the docs will not only be influenced by your feedback, but you're invited to contribute and help shape our documentation.
