I'll give you 2 examples and tell me which is more readable:

  console.log('start')
  doA()
    .then(() => {
      doB()
       .then(() => {
          doC()
           .then(() => {
             console.log('finish')
        })
      })
    })
    .catch((error) => {
      console.log(error)
    })

Or

  console.log('start')
  try {
    await doA()
    await doB()
    await doC()
    console.log('finish')
  } catch (error) {
    console.log(error)
  }
