The goal of this serie of 3 pipe challenges is to master PIPES in Angular.

Pure pipe are a very useful way to transform data from your template. The difference between calling a function and a pipe is that pure pire are memoized. So they won't be recalculated every change detection cycle if the inputs hasn't changed.

## Information:

In this first exercice, you add calling a simple function inside your template. The goal is to convert it to a pipe.

## Constraints:

- must be strongly typed
