EventEmitter3 is a high performance EventEmitter. It has been micro-optimized

for various of code paths making this, one of, if not the fastest EventEmitter

### Tests and benchmarks
|
||||
|
||||
This module is well tested. You can run:
|
||||
|
||||
- `npm test` to run the tests under Node.js.
|
||||
- `npm run test-browser` to run the tests in real browsers via Sauce Labs.
|
||||
|
||||
We also have a set of benchmarks to compare EventEmitter3 with some available
|
||||
alternatives. To run the benchmarks run `npm run benchmark`.
|
||||
To run tests run `npm test`. To run the benchmarks run `npm run benchmark`.
|
||||
|
||||
Tests and benchmarks are not included in the npm package. If you want to play
|
||||
with them you have to clone the GitHub repository.
|
||||
Note that you will have to run an additional `npm i` in the benchmarks folder
|
||||
before `npm run benchmark`.
