async in array map code example
Example 1: nodejs await inside map
const someFunction = (myArray) => {
const promises = myArray.map(async (myValue) => {
return {
id: "my_id",
myValue: await service.getByValue(myValue)
}
});
return Promise.all(promises);
}
Example 2: map with async
const list = [1, 2, 3, 4, 5]
const functionWithPromise = item => {
return Promise.resolve('ok')
}
const anAsyncFunction = async item => {
return functionWithPromise(item)
}
const getData = async () => {
return Promise.all(list.map(item => anAsyncFunction(item)))
}
getData().then(data => {
console.log(data)
})
