Methods vs pipes

Question

Is there a difference between using a pipe and a method in template interpolation in an Angular application?

For example:

{{ name.toLowerCase

Answer 1

TL;DR; Don't use functions or methods in the template, use pipes instead.

A pipe would be called only when input values change. A function or a method would be called on every change detection. Here is a nice article if you want to know more about functions in template.

Here is a running stackblitz demonstration of method vs pipe.
