How to find matching items in an array using JavaScript

The Array.filter() method creates a new array by iterating over all elements of an array and returns those that pass a certain condition as an array.

The callback function passed as an argument takes in up to three optional parameters. The first is the current element in the iteration, the second is the index of the current item in the array, and the third is the array itself.

In the callback body, you can test if the current item matches what you're looking for, and return a boolean (true or false) accordingly.
