WrapFn pipe

Author: Thomas Laforge

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 second exercice, you add calling multiple functions inside your template. You can create a pipe for each of this function but this will be a bit too much to create that much specific pipe. The goal is to create a wrapFn pipe to wrap your function calls though a pipe.

Constraints:

• must be strongly typed
