Somehow webpack/JS/React has way faster build times than Java/Android apps. That's the main reason we completely abandoned fully native apps in Java/Swift in favor of webapps with a tiny native wrapper app for the few only-native calls we need.

And to move forward this trend, new bundlers are appearing in JS like esbuild/snowpack that are even faster than webpack.

This is why the web will always win in the long run. While the Android team in working on their tooling and Apple on other tooling and Windows on other tooling on the web all tooling is shared. You don't need the OS/platform gatekeeper to come up with faster bundlers. You just need one company/opensource team to make a breakthrough tool.

Finally this is the point why I believe TYPES ARE NOT WORTH IT. Types make the whole development slower. To me is better to be able to try and run the code faster in development and try it manually several times than to wait longer for type checks. Typing is overrated in my opinion.
