I rewrote the Pong game to WebGL 1.0 and TypeScript from the tutorial: https://noobtuts.com/cpp/2d-pong-game
I use a free hosting and sometimes my Node.js/Express server sleeps. Wait 10 second to wake up the server.

Run the release version in the browser: http://ivan8observer8.herokuapp.com/webgl10-ts/pong2d-from-noobtuts/

Download the source code: hhttps://github.com/8Observer8/pong2d-from-noobtuts_webgl10-typescript

I will find the instruction in README.md file how to build to the Release and Debug versions.
