2.2.0

New Features

• support for wrapping an asynchronous function

Before if we want to wrap an async value, we need to get the promise value first, then pass it to the wrap function, like this

const v = Promise.resolve(1)

wrap(v).unwrap()

But this is not that convenient if we want to just wrap an async function so that others can use it without the need to wrap it explicitly. Not the wrap function accepts async function.

import {wrap} from 'unwrapit'

const fetchWrapper = wrap(fetch)
const ret = (await fetchWrapper('www.google.com')).unwrap()
const json = await ret.json())

Now you can share a wrapped async function with others, and it will be wrapped with Result types naturally.
