can use async in the map code example

Example 1: async map js

Arr = await Promise.all(arr)

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
*/
