object is anything people want to study, from the simplest integer to the complex plane can be regarded as an object, it can not only represent the specific things, but also can represent abstract rules, plans or events. --Quote from Baidu Encyclopedia Object-oriented programming is the most popular programming mode at the moment. But sadly, the most widely used JavaScript as a front-end does not support object-oriented.

sequence like the original function. Since it is an array, It is controllable. An array is generated based on other functions or logic judgment, which can pass in the dynamic number parameter. However, I encountered a headache. I had to input a dynamic parameter when I used new to create an object. This problem occurred only a few years ago: If ES6 is used and the rest parameter is used, all the above problems are not a problem. Note: adding three

Three ways to define JavaScript classes (Class) Almost 20 years ago, when JavaScript was born, it was just a simple web scripting language. If you forget to fill in the user name, it jumps out a warning. Today, it becomes almost omnipotent, from the front-end to the back-end, with a variety of unthinkable uses. Programmers use it to accomplish larger and larg

Overview What are we talking about when we're talking about object-oriented programming? The first thing we talk about are concepts: objects, classes, encapsulation, inheritance, polymorphism. Objects and classes are object-oriented, and encapsulation, inheritance, and polymorphism are the three characteristics of object-oriented programming. JavaScript provides objects but lacks classes, and it cannot explicitly define a

Learn more about Javascript I 've been mixing up my script for a while recently and replied to some posts, but I didn't make anything to show it to everyone. I felt a little uneasy, so I wrote something below, it should have been sent in the class encapsulation area. Considering that it is cold, I hope this article can help more friends, so I will put it here. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>

Almost 20 years ago, when JavaScript was born, it was just a simple web scripting language. If you forget to fill in the username, it jumps out a warning. Today, it becomes almost omnipotent, from the front end to the back end, with a variety of unthinkable uses. Programmers use it to accomplish increasingly large projects. The complexity of JavaScript code also goes up in a straight line. A single Web

Javascript itself does not support object-oriented features. It does not have an access control operator and does not define the class keyword. It does not support inherited extend or colons, nor does it support virtual functions, however, Javascript is a flexible language. Let's take a look at how Javascript without a

What is a class? Many friends who are new to programming may not understand the class. In fact, the class is a simulation of our real world. It may be easier to say "category" or "type. For example, an animal like "man" is a class, and a specific person is an instance of "man". "Man" can have many instances (more t

In writing work-in-progress JavaScript book, I spent a considerable amount of time on the JavaScript inheritance system, and studied various scenarios for simulating classical class inheritance in the process. In these technical projects, I most highly esteem is the BASE2 and the prototype realization. From these solutions, one should be able to extract a framew

When you use some Javascript frameworks, you may see similar code Copy Code code as follows: var MyClass = new Class ({ Initialize:function (param, ...) { This.param = param; ... }, Func1:function (...) { ... } }); var myobj = new MyClass (param); MYOBJ.FUNC1 (...); This is a typical object-oriented application of the class
