tryit

Usage

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

The tryit function let’s you wrap a function to convert it to an error-first function. Works for both async and sync functions.

import * as _ from 'radashi'

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

Currying

You can curry tryit if you like.

import * as _ from 'radashi'

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

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