Node.js Tutorial — Run an Async Function in Array.map()
Array.map() in Node.js/JavaScript is a synchronous operation and runs a function on each element in the array resulting in a new array with the updated items.
Let’s run asynchronous functions in Array.map() with the help of Promises!
There are situations where you want to run asynchronous functions within map, e.g. updating a list of models and push the changed information back to the database or request information from an API that you want to use for further operations.
