usage

By using a Maybe value, it forces us to handle both the cases where a value does exist, and where it doesn't. This is helpful for dealing with API's that return null/undefined values if they fail.

const list = [
  1,
  2,
  3,
]

const value = list.find(v => v === 4)

Maybe(value).match(
  // just callback
  (v) => {
    console.log(`we found a value: ${v}`)
  },
  // nothing callback
  () => {
    console.log('unable to find value :(')
  },
)
