2.1.0

Mitt 2 is out of preview!

• It's written in TypeScript and ships type definitions (#107, thanks again @jackfranklin!)

• Event handlers are now stored in a Map instead of an Object.

  Upgrading: If you aren't passing an object to mitt({}), version 2 is backwards-compatible.
  If you were, turn your object into a map:

  -const handlers = {
  -  foo: [() => alert(1)]
  -};
  +const handlers = new Map();
  +handlers.set('foo', [() => alert(1)]);
  
  const events = mitt(handlers);

• The event handler Map is now exposed as .all: (#105, thanks @jaylinski!)

  const events = mitt();
  events.on('foo', () => alert(1));
  events.on('bar', () => alert(2));
  
  // access handlers directly if needed:
  events.all.get('foo') // [() => alert(1)]
  
  // remove all event handlers:
  events.all.clear();
