January 6, 2014Ct.js — Visual game editor for Pixi.js
GitHub: https://github.com/ct-js/ct-js I think ct.js is a hidden gem amongst open source game tooling. Pixi is among the most mature and popular game engines available for 2D game development, but it doesn’t have an official editor. ct.js simply layers a whole suite of graphical interfaces on top of Pixi to make it accessible to a wider audience. The author is a classic “would rather spend time coding than doing PR” open source dev. I hope r/javascript can show some appreciation for their work! More on reddit.com

January 12, 2016How fast is the online JavaScript compiler?
PlayCode's compiler is optimized for speed. Initial compilation takes 100-500ms depending on project size. Incremental builds (when you edit code) complete in 20-50ms. That's often faster than running a local Node.js bundler because everything runs in memory with no disk I/O.

What is a JavaScript compiler?
A JavaScript compiler transforms your JavaScript code into optimized, executable code. Unlike traditional compilers that produce machine code, JS compilers like PlayCode bundle your code, resolve imports, and transpile modern syntax (ES2026, TypeScript, JSX) into browser-compatible JavaScript that runs instantly.
