Node.js is a powerful runtime environment for executing JavaScript on the server side. It’s used in various applications, from building web servers to running scripts. It’s important to know which version of Node.js you have installed as different projects might require different versions for compatibility. In this article, we’ll explain how to check your Node.js version from the command line. Before diving deep into it let’s talk about why knowing the Node.js version matters.
Why Knowing the Node.js Version Matters?
Below are some reasons why knowing the Node.js version is important.
1. Compatibility
Different projects or apps sometimes need a particular Node.js version to work properly. By knowing your version, you make sure you’ve got the right one for the job.
2. Security
Keeping Node.js up to date is like upgrading the lock of your house’s front door. Newer versions usually fix security issues from older ones, making your applications safer.
3. Performance
Think of updates like a turbo boost for your car. Node.js updates can make your apps run faster and smoother, giving your users a better experience.
4. Bug Fixes
No software is perfect, and bugs can pop up. Newer Node.js versions come with fixes for these bugs and other improvements, making sure your code runs without hiccups.
In a nutshell, checking your Node.js version is a small step that can have a big impact on your projects. It’s all about making sure your software runs well, stays secure, and plays nicely with everything it needs to.
Getting Node.js Version on the Command Line
