Node.js is a popular server-side JavaScript runtime that has been widely adopted by developers for building scalable and high-performance web applications. With the release of Node.js v20, there are several new features and improvements that developers should be aware of. In this blog, we will discuss the new changes in Node.js v20 compared to the old LTS version.
- V8 engine update Node.js v20 features an update to the V8 engine, which powers JavaScript execution in Node.js. This update brings significant performance improvements, including faster startup times, reduced memory usage, and better garbage collection. This means that Node.js v20 applications can handle more traffic and scale better than the old LTS version.
- Support for ECMAScript modules Node.js v20 has added support for ECMAScript modules, which are a new standard for organizing and sharing JavaScript code. This allows developers to write more modular and maintainable code, making it easier to collaborate and reuse code across different projects.
- Experimental Async Local Storage Node.js v20 introduces an experimental feature called Async Local Storage, which allows developers to store and access data across asynchronous contexts in a more efficient way. This can be particularly useful for tracing and debugging asynchronous code and can lead to better performance and fewer errors.
- Improved diagnostic reports Node.js v20 includes several improvements to the diagnostic reporting capabilities, making it easier to debug and troubleshoot Node.js applications. The new reports include more detailed information about errors and warnings, as well as recommendations for resolving issues.
- Updated platform support Node.js v20 includes updates to the supported platforms, including support for the latest versions of macOS, Windows, and Linux. This ensures that developers can build and deploy Node.js applications on the latest operating systems and take advantage of the latest features and improvements.
- In conclusion, Node.js v20 brings several new features and improvements that make it a compelling choice for building modern web applications. The new updates, including the V8 engine update, support for ECMAScript modules, experimental Async Local Storage, improved diagnostic reports, and updated platform support, provide developers with powerful tools to create scalable, high-performance applications. If you are currently using the old LTS version of Node.js, it’s worth considering upgrading to Node.js v20 to take advantage of these new features and improvements.

This is the single most widely-spread lie about NodeJS. It is ok, but there is literally 200 other technologies that outperform it.
True. and every other framework will claim itself high performance.
The best framework is the one in which you can create what you need with ease.
Also.
Not "highest performance". but just "high performance". I know big Nodejs codebase in the hands of a beginner is worth a burnt chip.
I don't know man. The list I saw was of about 500 different server setups. NodeJS started at position 212 (or 213, my memory is fuzzy right now). Where do we set the minimum for "high" performance? I think the 40th percentile is a bit of a stretch. High performers should be the top 10%, maybe even the top 20%. This is why I say "OK performance" because NodeJS roams the 40% mark.
