Bengular is a simple dev tool I made to create websites (even this one!). Supporting typescript, scss, dev serving and reloading, it's my go to for all web projects. It's open source and available on npm and github.
Screeps is a game for programmers. Players write their scripts to control their creeps, in a persistent MMO RTS. I've written my script in Typescript, bundling with Webpack.
One Function is a stupid project/experiment I did. It's an implementation of the traditional snake game, but all the code has to be written in one function, called recursively. Written in plain Javascript.
