[ ] write proper tests [ ] create package.json browser/react-native fields

one package but distinct include (import x from 'package/feature') with code removal? browser, electron, react-native keys?

package keywords

"test": "xo && ava && tsd-check"

travis? https://github.com/sindresorhus/delay/blob/master/test.js

arraybuffer-hex -> node way, TextEncoder way, fallback

arraybuffer-base64 -> same

arraybuffer-binarystring

arraybuffer-utf8
