JavaScript has no class statement, which is baffling for coders who are used to languages with a class statement; However, JavaScript has constructors to bring similar functionality. Constructors are just regular functions which are used withnewkeyword. They come in handy when we need to make multiple similar objects with the same properties and meth...

Constructor.DEFAULTS.keyboard = false // 将模态框插件的 `keyboard` 默认选参数置为 false 避免命名空间冲突 某些时候可能需要将 Bootstrap 插件与其他 UI 框架共同使用。在这种情况下,命名空间冲突随时可能发生。如果不幸发生了这种情况,你可以通过调用插件的 .noConflict 方法恢复其原始值。 var bootstrapButton ...
On the other hand, constructor functions are useful if you want to create multiple objects. For example, // use object literal to create // a single object person let person = { name: "Sam" } // use constructor function function Person () { this.name = "Sam" } // create multiple ...

一方面,JavaScript 有一些怪癖,缺少相当多的功能(块作用域变量,模块,支持子类等)。另一方面,它有几个强大的功能,可以让你解决这些问题。在其他语言中,你学习语言特性。在 JavaScript 中,你经常学习模式而不是语言特性。 鉴于它的影响,毫不奇怪 JavaScript 可以实现一种混合了函数式编程(高阶函数;内置的map,reduce等...

Class C uses the composition pattern to achieve a similar effect of multiple inheritances. The constructor creates instances of class A and class B and stores them as propertiesaandb, respectively. constructor(){this.a=newA();this.b=newB();} ...
