A code example from the article https://www.joshwulf.com/blog/2020/03/array-async-failure

async-either.js

async function myAsyncFunction(argument) {

  const success = async res => ({ success: await res }) // Promise<{success: res}>
  const error = async err => ({ error: await err }) // Promise<{error: e}>

  const arrayTasks = [
    { 
      run: async () => getDataAsync()
      }
    },
    { 
      run: async () => getDataAsync()
    }
  ]

   const runWithResult = task => task.run().then(success).catch(error)

   const outcomes = await Promise.all(arrayTasks.map(runWithResult))

   console.log(outcomes) // array of {error: e} | {success: res}

}
