You want fast view rendering and responsible view bindings are the first step to getting there.

// view markup
<Label text="{{getMyText}} />

// view binding class
export class ViewBinding extends Observable {
  getMyText() {
    return 'label text'
  }
}

This leads to developers doing logic in methods and can cause unnecessary view binding execution further slowing down your view rendering performance.

// view markup
<Label text="{{myText}} />

// view binding class
export class ViewBinding extends Observable {
  myText = 'label text'
}

This provides for direct 1-1 data projection to view binding resulting in no further JavaScript event loop cycles to process your view rendering.
