How to check Node version in cmd?


Node.js is an open-source, server-side runtime environment built on the V8 JavaScript engine developed by Google. It allows developers to run JavaScript code on the server, enabling the development of server-side and network applications. Node.js is known for its non-blocking, event-driven architecture, making it highly efficient for building scalable and real-time applications, such as web servers, APIs, chat applications, and more. It has a vast ecosystem of libraries and packages available through npm (Node Package Manager), making it a popular choice for modern web and application development.

To check the Node.js version installed on your computer using the Windows Command Prompt (cmd), you can use the following command:

Here are the steps:

  1. Open Command Prompt: Press Win + R, type “cmd,” and press Enter to open the Command Prompt.
  2. Check Node.js Version: In the Command Prompt window, simply type and execute the command node -v.

This command will display the Node.js version installed on your system, such as “v14.17.4.”
