How to Check Node.js and npm Version on Windows Machine Using Command Prompt

To begin, open the Command Prompt on your Windows machine. You can do this by searching for "Command Prompt" in the Start menu or pressing the Windows key + R, typing "cmd," and hitting Enter.

Once the Command Prompt is open, type the following command and press Enter:
node -v

Next, to check the version of npm installed on your machine, type the following command and press Enter:
npm -v
Similar to the previous command, this will display the version of npm installed on your Windows system. Again, the version number will be shown in the Command Prompt window.
