What is the difference between node.js and java

Difference: 1. Java is a programming language, and "node.js" is a JavaScript running environment based on the Chrome V8 engine; 2. Java is a server-side language, and "node.js" Can be used effectively on both client and server sides.

The operating environment of this article: Windows 10 system, nodejs version 12.19.0, Dell G3 computer.

What is the difference between node.js and java

Node.js was released in May 2009 and developed by Ryan Dahl. It is a JavaScript running environment based on the Chrome V8 engine and uses a The event-driven, non-blocking I/O model allows JavaScript to run on the server-side development platform, which makes JavaScript a scripting language on par with server-side languages ​​such as PHP, Python, Perl, and Ruby.

Java is an object-oriented programming language. It not only absorbs the various advantages of the C language, but also abandons the concepts such as multiple inheritance and pointers that are difficult to understand in C. Therefore, the Java language is powerful and easy to use. Two characteristics. As a representative of static object-oriented programming languages, Java language perfectly implements object-oriented theory and allows programmers to perform complex programming with an elegant way of thinking.

The difference between nodejs and java

1) Node.js is faster than Java:

node.js develops quickly and runs more efficiently It is relatively high, but if the project is large, it will be easy to mess up, and JavaScript is not a statically typed language. Type errors will not be known until runtime, so after writing too much, it is inevitable that you will know that there is an error but can't find where it is. situation, so the test needs to be better and more detailed.

Java development is slow, but if the project is large and complex, it will not be easy to mess up using Java, and it will be easier to manage than node.js.

2). Both the front and back ends of Node.js use Javascript, which represents the future development trend, and java is now the most popular server-side programming language.

3), Node.js and Java EE - one is an interpreted language and the other is a compiled language.

Node.js solves problems 20% faster than Java EE. An interpreted language is as fast as a compiled language in a VM, which is absolutely impossible to achieve without years of optimization.

4), Java is a programming language, and NodeJS is a JavaScript running environment written in C and based on the Chrome V8 engine.

5), Java is strictly a browser-independent server-side language, while Node JS can be used effectively on both the client and server sides.
