In this chapter, you will learn about Angular pipes. Think of Angular pipes as a modernized version of filters, comprising functions that help us to format the values within the template. Pipes in Angular are basically an extension of what filters were in Angular v1. There are many useful built-in pipes we can use easily in our templates.
