Node.js: Node.js 是一个用于创建运行时应用程序的库。它最初由 Rayn Dahl 编写,用于在浏览器外使用 JavaScript,后来由 Joyent 管理。 Node.js 用于前端和后端,开发人员也可以构建移动应用程序。凭借它的能力,它可以处理服务器端,用户可以请求一个数据包,同时它可以访问数据库。 JavaScript 有很多基于 Express.js 和 Node.js 的框架。但是当根据应用程序的类型决定使用这些框架时。这是 node.js 的一个优势,它可以使用 API 连接到设备,也可以连接到其他语言编写的库。
示例:在 Node.js 中打印“Welcome to GeeksforGeeks”。
javascript
// Syntax to print
console.log("Welcome to GeeksforGeeks");
Java
// Syntax to print
System.out.println("Welcome to GeeksforGeeks");
Java : Java是由 James Gosling 在 Sun Microsystems 开发的,后来被 Oracle 接管。 Java是一种面向对象的语言,其大部分语法源自 C++,其概念保持不变,但有一些修改。整个Java与称为Java Development Kit 的 JDK 捆绑在一起,足以运行一个Java程序。用Java编写的代码被转换成字节码,可以在任何机器上运行,而不管使用Java的操作系统如何,这是这种语言的最大优势之一。 Java拥有庞大的社区,并且支持网络和 GUI。许多游戏都是基于Java构建的,并且被广泛使用。有几个框架是基于Java构建的,用于 Web 开发,用于服务器端示例 Spring。
示例:在Java打印“Welcome to GeeksforGeeks”。
Java
// Syntax to print
System.out.println("Welcome to GeeksforGeeks");
Node.js 和Java 的区别:
Basis of | Node.js | Java |
---|---|---|
Application Type | Server-side applications that are highly scalable. | Highly complex applications have been created. |
Creation | Resembles the C, C++ and JavaScript conventions as framework is written in these. | Object oriented structure applications derived from C++. |
Installation | This requires to install npm to run Node.js. | It requires JRE to run Java. |
Developers Usage | It is used for small projects and server-side interactions. | It is used for CRUD operations based projects which are complex to handle. |
Community Support | There are a huge community to support. | Java community has been the most versatile so far and has huge supporter’s too. |
Frameworks | It has many frameworks such as Sails.js, Express.js, and Partial.js | It has frameworks named JSF, Struts, Hibernate, etc. |
Application | Used in applications where real time data is modified example Google Docs. | Used in applications where object creation is needed and data is managed. |
