The first version of Vue came bundled with some text filters that helped format text and solve some common problems.
In this new version, there are no built-in filters (except the equivalent of the JSON filter covered in the next recipe). I think this is because it's very easy to write your own filter and also very easy to find online libraries that do a much better job in specialized situations. Finally, filters have somewhat changed purpose: they are more for post-processing now and less for actual filtering and sorting arrays.
To demonstrate how easy it is to create a filter, we will recreate a filter of the old version of Vue: capitalize.
