Editor to share with you why to use nodejs, I believe that most people do not know much, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The reasons for using nodejs: 1, Node.js uses JavaScript on both the server side and the client side, which means that developers only need to use one language on each layer; 2, the development efficiency of node is very high and has the ability to build complex systems; 3, it can solve the IO-intensive problem very well; 4, the learning cost is low.

This tutorial operating environment: windows7 system, nodejs version 12.19.0, DELL G3 computer.

Node.js is a JavaScript running environment based on Chrome V8 engine and a development platform for JavaScript to run on the server side. It makes JavaScript a scripting language on a par with server-side languages such as PHP, Python, Perl, Ruby and so on.

Reasons for using Nodejs:

1. Front-end / back-end development uses the same language

Technologies like ASP.NET or Spring require developers to learn a new server-side language, such as Cumminary VB.NET or Java. Node.js uses JavaScript on both the server side and the client side, which means that developers only need to use one language at each layer.

2. Dynamic language:

Development efficiency is very high, and the ability to build complex systems, such as ql.io.

3. Performance and Istroke O load:

Nodejs solves the IO-intensive problem very well, which is realized by asynchronous IO.

4. Memory cost of the connection:

Each Node.js process can support more than 120000 active connections, and each connection consumes about 2K of memory.

5. the cost of learning is low.

Node is developed using js. You only need to learn simple api, so front-end developers can use it without barriers, and the learning cost is very low.

Moreover, Node has an active community and a rich pool of modules, with many off-the-shelf functional implementations. In terms of framework, there are also mature basic frameworks such as koa,express and secondary packaging frameworks such as egg, which can be chosen according to needs and are convenient to use.

6. The community of Nodejs is growing, not only the number of packages is increasing rapidly, but also the quality of packages is obviously better than that of other languages.

Many star packages are simple and smart, designed for developers' habits. The toolkits I use most often, such as socket.io, moment.js, underscore.js, async.js, express.js, bower.js, grunt.js, forever.js... It's really changing my previous programming habits.

7. A wide range of code hosting services are supported

Some Web servers and cloud service providers support Node.js 's Web applications. Let's talk about a few here, including Google,Microsoft IIS,Heroku,Microsoft Azure,Amazon (AWS) and so on.

The above is all the contents of the article "Why use nodejs". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
