@HostBinding and @HostListener: what do they do and what are they for?

Question

In my meanderings around the world wide interweb, and now especially the angular.io style docs, I find many references to @HostBinding and @HostListener

Answer 1

A quick tip that helps me remember what they do -

HostBinding('value') myValue; is exactly the same as [value]="myValue"

And

HostListener('click') myClick(){ } is exactly the same as (click)="myClick()"

HostBinding and HostListener are written in directives and the other ones (...) and [..] are written inside templates (of components).
