Which version of nodejs is best?

Node.js, as a JavaScript running environment, has become one of the daily essential tools for Web developers. With the continuous update and development of Node.js, we often encounter a problem, namely: which version of Node Is .js best? This article will explore this issue and make some suggestions for readers' reference.

First, a very obvious answer: the latest version of Node.js. The Node.js changelog shows that each version fixes some problems, adds new features, improves performance, and more, so the latest version is usually the best choice. The latest version is Node.js 14 (as of the time of completion of the article). Its important features include:

1. The V8 engine has been upgraded to version 8.1, which greatly improves the execution performance of JavaScript;
2. Support native readable and writable stream stopping;
3. Support for Windows native modules has been improved;
4. Debugging tools support checking collection type objects;
5. Support using zero HTTP upload in copy mode;
6. The multi-threaded experimental Worker is now a stable feature.

However, sometimes we may need to run some old programs or specific applications on an old version of Node.js. At this time, how should we choose the version of Node.js? In this case, we recommend solving the problem by using an LTS (Long Term Support) version of Node.js.

The LTS version, after a long period of stable testing, will become a version that may last several years, constantly getting security updates and bug fixes, but no new features will be added. The current LTS version is Node.js 12 (as of the time of article completion), its features include:

1. supports the default URL parser;
2. provides a way to support and parse international ized domain name (IDNA) API;
3. strengthens the ability to integrate social media platforms;
4. introduces Worker marked as experimental features.

In addition to the above recommended versions, Node.js also has some other versions, such as the currently maintained version Node.js 15, etc. For these other versions, we should comprehensively consider them from multiple perspectives such as usage scenarios, features, ecosystem, etc., and then choose the version that suits us.

In summary, for different situations, the version selection of Node.js is also different:

1. If you want to get the best performance, security and functionality, it is recommended to use the latest version Node.js.
2. If you need to take into account compatibility, stability and security, it is recommended to use the current LTS version.
3. In addition, for some specific scenarios, it may be more appropriate to use other versions.

Finally, it’s important to note that when you upgrade your Node.js version, you should carefully evaluate whether your code base and applications need to be updated and test whether they still work in the new version. Run correctly. Therefore, we recommend conducting some sufficient testing before upgrading to avoid unnecessary anomalies.

In general, which version of Node.js is best depends on the actual situation. When choosing a version, various factors should be taken into consideration. We hope this article can provide readers with some reference and suggestions.
