By now you should definitely know what a filter does and why it is so helpful, but let's recap everything we've covered in this chapter.
We started off by looking at how a filter is applied directly from our view using the pipe symbol syntax and separating any arguments with a colon. Once we had the basics covered, it was time to look at the numerous included filters.
A few filters were basic, not requiring any arguments at all, but we also looked at some of the more advanced filters that allow us to order or filter an array of objects.
Apart from applying filters from the view, we also looked at two methods of filtering from our controller. We could either use the included
$filter service or choose to inject our filters separately.
