I implemented my first ever (finished) HTML5 game called Laser Defence.
I used PIXI.JS v4 and TypeScript for the implementation. Visual Studio Code was used as the IDE.
For fun, I wrapped the project into Cordova and published it to the Google Play Store:
I had some issues with consistent frame-rates using Cordova on my Galaxy S5 phone. The fix was to use the Crosswalk Cordova plugin. This plugin comes with its own Chromium instance, which is far superior to the default webview provided by Android 6.0.
The con is a fatter APK, about 20MB - but the pro is a much more consistent experience.
