SOLID 原则是面向对象设计的五个基本原则,旨在帮助开发者创建可维护、可扩展和可重用的代码。虽然这些原则起源于面向对象编程,但它们可以有效地应用于JavaScript。本文通过JS中的真实示例解释了每个原则。 1.单一职责原则 (Single Responsibility Principle, SRP) ...
里氏替换原则(Liskov Substitution Principle - LSP) 接口隔离原则(Interface Segregation Principle - ISP) 依赖倒置原则(Dependency Inversion Principle - DIP) 在JavaScript 和TypeScript 中,尽管它们是动态语言且不以类为核心,但这些原则可融入组件化和模块化架构,开发者能借此确保代码简洁、可扩展、易维护和测试 一...
This is the fourth part of SOLID Principles in JavaScript. In Javascript we have something similar to them, it's classes, but this principle could be applied to JS classes. It means that when we create a base class, we should declare all methods that will be used in subclasses and try ...
Since JavaScript does not support interfaces, it is difficult to adopt this principle in JavaScript-based applications. However, we can use JavaScript compositions to implement this. Compositions allow developers to add functionalities to a class without inheriting the entire class. For example, assume...
接口隔离原则(Interface Segregation Principle):定制客户端的细粒度接口,不应强迫客户端依赖于不使用的接口。该原理解决了实现大接口的缺点。 让我们看下面的IShape接口: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 interface IShape { drawCircle(); drawSquare(); drawRectangle(); } 该接口有绘制正方...
单一职责原则是最简单的面向对象设计原则,它用于控制类的粒度大小。单一职责原则定义如下: 单一职责原则(Single Responsibility Principle, SRP):一个类只负责一个功能领域中的相应职责,或者可以定义为:就一个类而言,应该只有一个引起它变化的原因。 ...
单一功能原则 Single Responsibilty Principle “...You had one job”---Loki to Skurge in Thor: Ragnarok 一个类只做一件工作 一个类只负责一件事。如果一个类有多项责任,它就变耦合了。一个功能的变动会造成另外一个功能改变。 注意:这条原则不仅仅适用于类,也适用于软件组件和微服务。

SolidJS usescreateSignalto achieve the ability similar to ReactuseState, although it looks similar, but the implementation principle and the mind when using it are completely different: const App = () => { const [count, setCount] = createSignal(0); ...
