Question

JavaScript

Write out a function that takes in array of numbers. You do not need to check if each item of the array is a number, assume this has already been done. Create a new array using the map function that that the original item and adds 4 to it. Then iterate through the new array and log each item to the console. If you do not use map it will be counted wrong.

Call your function with the following array of data and write a comment with the outputted result  (e.g. do the math).

[4, -4, 10, 203, 53, 11]
