In Angular, why use a pipe instead of a native JavaScript function?

What is the advantage of using an Angular pipe when a comparable native JavaScript function exists? For example:

<input type="text" [value]="foo | uppercase">

vs.

<input type="text" [value]="foo.toUpperCase()">

pipe decorator @Pipe has pure option which is if false will listen to your changes of the variable passed in and rerun the pipe

With pure: false the pipe is evaluated each time Angular runs change detection.

also with toUpperCase() supose view will not evaluate your ts variable again
