Edge is macOS/Windows only but VSCode is available over there. Worth keeping an eye out because I wouldn't be surprised if Edge lands on desktop Linux[0] someday. I'm not a web developer and a Firefox diehard for almost 20 years now, but the Edge beta has become my fulltime Chrome alternative when I feel I need to try something on a Chromium-based browser.
