Is there an angular.noop for Angular 6?

Question

In my Angular 6 application, I need a function that does nothing. Obviously, I could just write my own, but I was reading about angular.noop which I would like to use. However, I get an angular.noop is not a function error when I try to use it. I could not find anything about this in Angular's documentation. Is there an Angular 6 version of AngularJS's angular.noop function?

I know what noop is. This is not a duplicate of What is Angular.noop used for?. I am asking about Angular 6. My question is very simply "Is there a noop function built into Angular 6 like there is in AngularJS?".

Please show in the question how you want to use that function. — ConnorsFan, Oct 12 '18 at 15:51
@ConnorsFan What difference does it make? All I want to know is if there is an equivalent function in Angular 6. — Stack Underflow, Oct 12 '18 at 15:51
@SiddAjmera No, I saw that. I know what the function is. That question is for AngularJS. Mine is regarding Angular 6. — Stack Underflow, Oct 12 '18 at 15:53

You could use noop which is a helper function from Rxjs for this:

import { noop } from 'rxjs';
...
// this does nothing.
noop();

I don't really think Angular has noop

This does nothing:

()=>{}

It's no more characters than noop() and doesn't need an import.

No. There is not a noop function in Angular 6.

I'm assuming you want to use this with (click). Try:

(click)="!!false"

it works and the compiler doesn't complain. Maybe there is a more semantic solution.
