txiki.js — The tiny JavaScript runtime

txikia (Basque): small, tiny.

txiki.js is a small and powerful JavaScript runtime. It targets state-of-the-art ECMAScript and aims to be WinterTC compliant.

It's built on the shoulders of giants: it uses QuickJS-ng as its JavaScript engine and libuv as the platform layer.
