Recursively flatten an array or arrays. This is the fastest implementation of array flatten.
Why another flatten utility? I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.
npm run benchmarks

Install dev dependencies:
npm i -d && npm test
npm i arr-flatten --save
bower install arr-flatten --save
var flatten = require('arr-flatten'); flatten(['a', ['b', ['c']], 'd', ['e']]); //=> ['a', 'b', 'c', 'd', 'e']
