Basic usage

Error-first callbacks were cool. Using mutable variables to hoist state when doing try/catch was not cool.

The _.try function let’s you wrap a function to convert it to an error-first async function.

import * as _ from 'radash'

const [err, user] = await _.try(api.users.find)(userId)

Note, because try is a reserved word this function is aliased as try and actually named tryit in the source.


You can curry try if you like.

import * as _ from 'radash'

const findUser = _.try(api.users.find)

const [err, user] = await findUser(userId)


This _.try function is 100% covered by tests. See them and contribute at GitHub.
