async_promise_all.js

import axios from 'axios' 

let myData = [{id: 0}, {id: 1}, {id: 2}, {id: 3}]

async function fetchData(dataSet) {
    const pokemonPromises = dataSet.map(entry => {
        return axios.get(`https://ironhack-pokeapi.herokuapp.com/pokemon/${entry.id}`)
    })

    const results = await Promise.all(pokemonPromises)
    
    results.forEach(result => {
        updateData(result.data)
    })
    
    console.log(myData) 
}

function updateData(newData) {
    myData = myData.map(el => {
        if(el.id === newData.id) return newData
        return el
    })
}
    
fetchData(myData)
