Introduced State mode allows an object to change its behavior when its internal state changes, and the object appears to modify its class. Body For example, as we normally download things, there are usually several states, such as preparation

[About modularization and why modularization] Let's first explain why we need to be modularized. In fact, this is still related to the coding idea and the convenience of code management (the problem of namespace pollution is not mentioned because I

"About modularity and why to Modularize" Let's talk about why we want to modularize. In fact, this is related to coding ideas and the convenience of code management (no mention of namespace pollution is because I believe that the coder who has

At the same time, we know that in object-oriented high-level languages, creating objects that contain private members is one of the most basic features, providing properties and methods to access private members to hide internal details. Although JS

At the same time, we know that in the object-oriented advanced language, creating an object containing private members is one of the most basic features. It provides attributes and methods to access private members to hide internal details. Although

Introduced Combined mode (composite) combines objects into a tree structure to represent a "partial-whole" hierarchy, which makes the user consistent in the use of individual objects and composite objects. The common scene has the control

If the keyword Error is used for an exception, we can create an exception instance like a new common object. var err = new Error ("this is an exception"). The attribute of the exception is as follows: description: error description fileName:

One of the most common technical tools for implementing control reversal in object-oriented programming (inversion, hereinafter called IOC) is that dependency injection (Dependency injection, hereinafter called DI) is a great way to go in OOP

Interfaces are one of the most useful features in the object-oriented Javascript toolbox. As we all know, in the design mode, GOF says: interface-oriented programming, rather than implementation-oriented programming, is enough to show how important

This article summarizes common dependency injection methods in Javascript and uses inversify. js is used as an example to describe how the dialect community tries to use the DI framework in Javascript and its initial results as an Inversion of

Is enough to show how important an interface is in an object-oriented domain. But JS does not have built-in interface mechanisms like other object-oriented high-level languages (c#,java,c++, etc.) to determine that a group of objects and another

I recently read the book "Pro JavaScript design pattrens" in the Javascript design mode. I think it is very good and can improve my understanding of JS oo, it may also help you better understand the JS library written by others and improve your JS

The first important content in this book is interfaces.Everyone should be familiar with Interfaces. Simply put, interfaces are a contract or specification. Interfaces can be easily implemented in a strong facial object language. However, there is no

In practice, we can define interfaces in annotations and implement them in actual code. Like what: Copy Code code as follows: /* Interface Composite { function add (child); function remove (child); function Getchild (index);

I recently read the javascript design patterns book projavascriptdesignpattrens. I think it is very good. It can improve my understanding of jsoo and help me better understand the jslibrary written by others, improve your js level. This book is the

The first important element in this book is the interface. We should be familiar with the interface, simply say that the interface is a contract or specification. In strongly typed object-oriented languages, interfaces can be easily implemented.

In the previous period, we discussed the design of the queue management component and gave it a loud and unique name: SmartQueue. this time, we will put the previous design results into practice and use code to implement it. First, we need to
