Better-Mitt: A tiny (~400B) TypeScript-first event emitter that improves on Mitt

I built this as an improved version of the popular Mitt library. It keeps the tiny footprint (~400 bytes gzipped) while adding genuinely useful features that I found myself needing in real projects:

- once() for one-time listeners - hasListeners() and listenerCount() for introspection - clear() to reset everything - Safer emission that protects against handler modification during events - Full TypeScript support with generic types

Same familiar API as Node's EventEmitter and original Mitt, so it's a drop-in replacement. I've been using it in production and it's been solid.

NPM: npm install better-mitt

Would love feedback from the community - and if you find it useful, a GitHub star would be much appreciated!

I guess the increase in bytes was because of the added functionalities?
