$ npm add maeby
# or
$ yarn add maeby
import { maybe, just, nothing } from 'maeby'
const flakyCaps = name =>
Math.random() > 0.5 ? name.toUpperCase() : null
maybe(flakyCaps('hey'))
.bind(curtGreeting => `${curtGreeting}! how's it goin?`)
// ^ equivalent to:
// .bind(curtGreeting => just(`${curtGreeting}! how's it goin?`))
.unwrap()
// ^ convert back to the plain unwrapped JS value
