JavaScript: is return await needed? sometimes.

returnAwait.js

// INCLUDING AWAIT DELEGATES TO PARENT
const dontBubbleUp = async () => {
  const samplerPack = async () => {
    throw new Error('BAD')
  }
  try {
    return await samplerPack()
  } catch (e) {
    throw new Error('handling rejection upstream in parent')
  }
}
dontBubbleUp()
  .then(res => console.log('End of chain reached.', res))
  .catch(err => console.log('YOLO TEST 1:\n', 'End of chain reached.', err))

// EXCLUDING AWAIT HANDLES FIRST AT CALL SIGHT
const bubbleUp = async () => {
  const newSamplerPack = async () => {
    throw new Error('handling error in newSamplerPack first')
  }
  try {
    return newSamplerPack()
  } catch (e) {
    throw new Error('handling error locally')
  }
}
bubbleUp()
  .then(res => console.log('End of chain reached.', res))
  .catch(err => console.log('YOLO TEST 2:\n', 'End of chain reached.', err))
