Add modifier method

[bobisjan]

What do you think about adding modifier "shortcut" method?

Similar to Helper class and helper method, the modifier method would be useful for common use cases.

Usage

// app/modifiers/scroll-top.js
import { modifier } from 'ember-oo-modifers';

export default modifier(function scrollTop(element, [scrollPosition]) {
  element.scrollTop = scrollPosition;
});

Implementation

// addon/-private/modifier.js
import Modifier from './modifier-native';

export default function modifier(modifierFn) {
  return class extends Modifier {
    didReceiveArguments(positional, named) {
      modifierFn(this.element, positional, named);
    }
  }
}
