/**
|
|
* Creates an object which can listen for and emit events.
|
|
* This is similar to the EventEmitter API in Node's standard library, but it has a few differences.
|
|
* The goal is to allow multiple modules to attach arbitrary listeners to the same emitter, without
|
|
* letting the modules know about each other at all.
|
|
* 1. It has no special keys like `error` and `newListener`, which would allow modules to detect when
|
|
* another module throws an error or registers a listener.
|
|
* 2. It calls listener functions without any `this` value. (`EventEmitter` calls listeners with a
|
|
* `this` value of the emitter instance, which would give listeners access to other listeners.)
|
|
* @returns {SafeEmitter} An emitter
