Overview of node.js’s future

Node.js tops the list of the most popular Web Framework for Web App Development, according to Stack Overflow Developer Survey 1 2020. The turnout was 51.9 percent. Since 2020, more and more companies have rapidly transformed Node.js, such as Yahoo, Wal-mart, Uber and so on.

Why node.js is selected

Node.js helps enterprises solve a range of production problems and challenges, some of which are platform-related and some of which are related to resource utilization. Netflix, Paypal, Linkedin, and others all report that Node.js can save up to 60% of startup time 2.

The graph below shows developer statistics on node.js’ impact on development. As you can see, most developers think Node.js will speed up development, reduce development costs, and improve application performance. In addition, 22% of developers said it was easier to hire the right people using Node.js, which means node.js is easier to use than other languages such as Java, PHP,.net, and lighter and simpler than Java Spring. SIMFORM has done a survey of 15 companies’ views on Node.js 3.

The advantage of the Node. Js

High performance real-time applications

One advantage of Node.js is the ability to quickly build applications and display results. Node.js is powerful because it is based on Chrome’s V8 engine and written in C++, which compiles functions to machine code with extraordinary efficiency. To ensure continued improvement, Google uses the V8 benchmark suite to improve Node.js performance with faster execution times, better compilers, security patches, and scalability.

More scalable modern applications

Cutting-edge technology brings thousands of features, such as cluster Modules. It facilitates load balancing on multi-core cpus, making it easier to fulfill requirements through smaller modules without burning out memory processes. In addition, Node.js uses a non-blocking time loop to improve scalability, allowing the server to handle requests seamlessly.

From an evolutionary point of view, Node.js supports microservices well, allowing applications to be broken down into smaller parts. Node.js and microservices allow modern applications to scale on demand, helping companies achieve higher performance with fewer resources.

Easy to learn and quick to get started

Javascript is one of the most popular and widely used programming languages in the WEB developer community, and getting used to and learning Node.js is a breeze for WEB developers, with less time to write code. According to Node.js user Survey 2016 4, Javascript is the most popular front-end development language and requires less time and experience to learn and use Node.js. According to a recent StackOverflow survey, a staggering 49.9% of professional developers polled chose Node.js as the most commonly used technology.

The shortage of the Node. Js

1. Performance degradation for complex computing tasks: When a node.js event loop receives a fairly large CPU-driven task, it uses all of its CPU resources to complete it. (You can do complex computations in other languages that Node.js is not good at.)
2. API instability leads to heavy code change overhead: Node.js is often not backward compatible and requires significant changes when updated to a new version. (Node.js is a relatively new language and still thriving.)
3. Asynchronous programming makes code hard to maintain: two words — callback hell. (Note: This has now been resolved by Promise, but this problem may occur in some libraries before promises appear. It is recommended to use newer, long-term maintained libraries.)
4. Lack of library support can affect code quality: there are many low quality and rotten libraries on NPM, and the lack of documentation can lead to product code confusion and irregularities.
