node-eventemitter3 - 4.0.7-1 main

EventEmitter3 has been micro-optimized for various code paths making this, one
of, if not the fastest EventEmitter available for Node.js and browsers. The
module is API compatible with the EventEmitter that ships by default with
Node.js but there are some slight differences.
.
It is a drop in replacement for existing EventEmitters, but just faster.
The EventEmitter is written in EcmaScript 3 so it will work in the oldest
browsers and node versions that one might need to support.
.
Node.js is an event-based server-side JavaScript engine.
