_Coldzer0_ is working on an integration of _Castle Game Engine_ and QuickJS, a [powerful JavaScript engine](https://bellard.org/quickjs/).

1. [Check out this demo how to use JavaScript as a scripting language in your game](https://github.com/castle-engine/quickjs-demo/). It shows how to execute a JavaScript from a Pascal program, and also provide some functions to be called from JavaScript (and handle them in Pascal). So we have a bi-directional integration with JavaScript.

2. As a next step, _Coldzer0_ is working on exposing Castle Game Engine API in JavaScript. The idea is to allow to code a complete game using JavaScript, if you prefer/know this language better than our Pascal 🙂
