We will finish up on the built-in filters with a look at the limitTofilter. This handy filter lets you limit the amount of
information displayed from an array. It does this by creating a new array, which contains a subset of the items that are
contained in the original array. To showcase the usefulness of this filter, we will add a new property to our sample data
source. This new property will contain the customer’s historical data usage for the last 12 months. Listing 4-6 is the
controller, revised to show this new property.
