import axios from 'axios'
const API_ENDPOINT = 'https://sample-flights-api.com/cities/'

async function getAirports (cityCodes) {
  let promises = []
  let airports = []
  cityCodes.forEach(city => {
    let promise = new Promise(async (resolve, reject) => {
      try {
        let { data } = await axios.get(`${API_ENDPOINT}city`)
        airports = [...airports, ...data]
        resolve()
      } catch (err) {
        reject(err)
      }

    })
    promises.push(promise)
  })

  try {
    await Promise.all(promises)
    return airports
  } catch (err) {
    console.log(err)
  }
}

const cities = ['ABV', 'LOS', 'ENU']
// whatever we want to do with the list of airports, maybe just write them out to the console
console.log(getAirports (cities))
