rambdax/src/tryCatch.js

Extended version of Rambda - a lightweight, faster alternative to Ramda

import { type } from './type.js'

const isFunction = x => [ 'Promise', 'Function' ].includes(type(x))

export function tryCatch(fn, fallback){
  if (!isFunction(fn)){
    throw new Error(`R.tryCatch | fn '${ fn }'`)
  }
  const passFallback = isFunction(fallback)

  return (...inputs) => {
    try {
      return fn(...inputs)
    } catch (e){
      return passFallback ? fallback(e, ...inputs) : fallback
    }
  }
}
