executes a function and return go like array, first success return, second the error if any (inspired by https://www.npmjs.com/package/try)

t.js

export const t = async (f) => {
  let output = undefined
  let error = undefined

  try {
      output = f()
  } catch(e) {
      error = e
  }

  return [output, error]
}

usage.js

import { t } from './t.js'

const main = async () => {
  const goodFunk = () => 'good'
  const badFunk = () => 'bad'.dontHaveAMethod()

  const [goodOutput, err] = await t(goodFunk)

  if (!err) console.log(goodOutput)

  const [badOutput, badError] = await t(badFunk)

  if (badError) console.log('We need to talk about the bad funk')
}

main()
