javascript - Backbone : properties in ECMAScript 6

Question

我正在寻找与以下主干代码等效的良好 ECMAScript 6:

var MyModel = Backbone.Model.extend({});

var MyCollection = Backbone.Collection.extend({
    model: MyModel
});

此模式广泛用于 Backbone 模型、 View 和集合中。 我能否比下面的代码做得更好(例如，通过创建一个名为“model”的方法)？

export class MyModel extends Backbone.Model {}

export class MyCollection extends Backbone.Collection {
    constructor() {
        super({model: MyModel});
    }
}

Answer 1

我会使用 setter/getter :

export class MyModel extends Backbone.Model {}

export class MyCollection extends Backbone.Collection {
  get model() {
    return MyModel;
  }
}
