• Install the latest version of Node.js: Use the command nvm install version (replace version with the version you want to install) to install the latest version of Node.js.
• Switch to the new version: Once the installation is complete, use the command nvm use version to switch to the new version of Node.js.

Method 2: Using Package Manager

Another method for updating Node.js is to use your operating system’s package manager. Here’s how to update Node.js using a package manager:
