filter() - JavaScript Array Methods
filter() will return a new array, with some elements potentially filtered out. The new array will keep only those values by which the filter function, run against that value, returns true. If the filter function returns false for a value, it will be filtered out, and not included in the new result array. Use can use filter in many situations, one that I've found I encounter often is when I have an array of objects. I can call filter() on that array to return a new array with only the objects that I want to use.
