In the third installment in his deep dive into AngularJS, Jeremy covers filters. Filters provide a declarative way to format data in the presentation layer of Angular apps. XAML developers will recognize filters as an HTML version of value converters. Jeremy covers all of the filters that Angular ships with that format currency, dates, times, filter and sort lists, and much more. He then demonstrates how to write tests for filters and walks you through creating a custom filter of your own.
