Node.js: Node.js a library that is used to create runtime applications. It was initially written by Rayn Dahl for using the JavaScript outside the browser and later on it was managed by Joyent. Node.js is used for both front-end and back-end and developers can build mobile applications as well. With its capabilities, It can handle the server-side, a user can request a packet and at the same time, it can access the database. JavaScript has plenty of frameworks that are based on Express.js and Node.js. But when depending on the type of application these frameworks are decided to be used. This is an advantage of node.js that it can connect to devices using APIs and can connect to libraries written in other languages too.
Example: Printing ‘Welcome to Lazyroar’ in Node.js.
javascript
// Syntax to printconsole.log("Welcome to Lazyroar"); |
Java: Java was developed at Sun Microsystems by James Gosling and later on, Oracle took it over. Java is an object-oriented language whose most of its syntax is derived from C++ and its concepts remain the same with some modifications. Whole Java comes in a bundle with JDK called Java Development Kit, and it is enough for a java program to be get run. The code written in Java is converted into byte code which can be run on any machine irrespective of the operating system that has Java and this one of the biggest advantages of this language. Java has a huge community, and it supports networking and GUI. Many games are built on Java and are used extensively. Several frameworks are built on Java for web development, for Server-sideexample Spring.
Example: Printing ‘Welcome to Lazyroar’ in Java.
Java
// Syntax to printSystem.out.println("Welcome to Lazyroar"); |
Difference between Node.js and Java:
| 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. |
