Thanks to Kangax, webspacedspace, zloirock and the rest of the people who contributed to Kangax ES Compatibility Table

This site uses the base of the awesome compat-table and adds all the code to handle the additional testing on the NativeScript runtimes, and ability to export the data and collate it back to these tables...

[1] Since Apple does NOT allow JIT-able engines, WebAssembly cannot be supported on iOS!

[2] See issue NativeScript Issue 7085

[3] The older method of `frame.topmost().showModal` will fail on second modal, use `args.object.showModal` from whatever handler is calling it.
