in the world of frameworks it's obvious that

html in your JS > JS in your html.

angular is a mess. it's the java of web frameworks. if you want up be enterprise(tm) go for it. I’m convinced it's only a thing because it gives people job security since nobody else chooses to touch it.

I don't know what you guys are doing with your Angular buttons, or if you haven't looked at it since AngularJS (which I never used, so I don't know what it took there).

Adding a button to Angular is just adding a <button> to your template. If you want to use Angular Material, that's one additional import in your component's code file, and one additional attribute for that template's <button> element.

  import {MatButtonModule} from '@angular/material/button';

  <button matButton (click)="onClick()">Click me!</button>

Just at least have a look at the documentation or tutorial before spreading fibs like that.

There was also the actual Java of web frameworks, GWT
