wait for map to finish javascript code example

Example 1: await inside map js

const mapLoop = async _ => {
  console.log('Start')

  const promises = fruitsToGet.map(async fruit => {
    const numFruit = await getNumFruit(fruit)
    return numFruit
  })

  const numFruits = await Promise.all(promises)
  console.log(numFruits)

  console.log('End')
}

Example 2: js is map async

let obj = {
  one: 1,
  two: 2,
  three: 3
}

obj.map((element, index) => {
  // do something
  // return result
});

/*
  map() is a higher order function (a function that takes another
  function as a parameter) and as such is synchronous
*/
