author Joseph Zimmerman http://www.joezimjs.com Date Created March 2012 This article is the first of a series of articles that describe the common design patterns used by JavaScript. Design patterns are reliable programming methods that help ensure that your code is easier to maintain, expand, and detach, and that all design patterns are essential when creating large JavaScript applications, especially in large groups. Single case
Single-piece Mode To some extent, the single-piece mode restricts the creation of classes rather than improving the creation of classes, but it still belongs to the creation mode. The single-piece
The single state design pattern is also called a single case pattern: 1. Single State design mode meaning: The main function of a single state pattern is to ensure that in object-oriented programming, a class can only have one instance object. As an object's creation patte
