Ask HN: Best way to develop multi platform apps?

I was thinking of using Electron but see that a lot of people complain about it (memory hog, slow.. just saw it again in the slack thread). Previously I used Adobe Air (long back) but it too suffered from same issues. So what is the best way to create an app that can be compiled and distributed on Windows(exe), Macos (dmg), Android (apk), iOS (ipa?), Linux easily?
