JavaScript Array map method

All Arrays in JavaScript have a map method which allows us to loop through every element in the original array, perform some action and then generate a new Array based on our actions.
The primary difference is that the map function needs a return statement in order to create the new Array.

Your videos truly precise and explicit in terms of clear understanding the core subject matter. I wish more people find you and learn from you.

Most of the videos on .map are 10+ minutes. You explained it in an easy to understand way in less than 4! Well done!

let proc = data.map(function(item, index, array) {
return objCheck(item, index);
});
You can also call other functions from map() and return objects to the new array. Good video

Of all the array methods, it's the map method that I found a little daunting. In less than 4 minutes, it's now crystal clear.
