Interesting theory and thread: https://twitter.com/SwiftOnSecurity/status/10697763353362923... “This isn’t about Chrome. This is about ElectronJS. Microsoft thinks EdgeHTML cannot get to drop-in feature-parity with Chromium to replace it in Electron apps, whose duplication is becoming a significant performance drain. They want to single-instance Electron with their own fork”
The irony. They had HTA apps (running on IE engine which still work more or less, I replaced most default Win10 apps like the image viewer and the "groove" music player with a version of them built with HTA since they were slow as hell to start up) for 20 years already, they did barely anything with it, they didn't really invest seriously in a good browser engine (Edge isn't) and now all they can do is use Google's?…
Office is C++, with 85-95% code shared between Windows, OS X, Android, iOS and Web; with a very tiny presentation layer on top.
