The motivation part would be a long story :)
This brings us to the roadmap of Neo and to when we can be sure that our customers can use our sites written in Neo.
What I see now is "For the best user experience, you need to use Google Chrome with the following browser flag: chrome://flags/#enable-experimental-web-platform-features". Maybe this means that we should only wait for Chrome 80+ to be on most desktops.
Firefox: all I got there is a number of "SyntaxError: import declarations may only appear at top level of a module". Which version of Firefox do we have to wait for?
Safari: I don't own any device from Apple but a number of my customers do. I wonder if Neo works there.
Other browsers: I assume that all the chromium based browsers are going to be covered by the compatibility with Chrome 80.
Mobile: "The online demos are not optimised for mobile yet, please use a desktop browser!" Is it only a matter of CSS or is there something about webworkers on those platforms?
You can run the dist/development and dist/production versions of neo inside FF & Safari right now, the performance should be close.
Having 1 browser which fully supports it is enough for a great debugging experience. Obviously it would be nice if other browsers do catch up.
Mobile: I need to add support for touch events inside the main thread, which should be easy. On my todo list after the real world 2 app is done (want to focus on this one first, since it is meant to be a good starting point for new devs to get up to speed). The multithreading performance will be amazing on mobile.
