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...
