Go to the official Node.js website at https://nodejs.org.
On the homepage, you will see a big green "Download" button. Click on it.
You will be directed to the downloads page, where you will find different versions of Node.js available for download. Look for the latest LTS (Long Term Support) version, which is currently Node.js 14.x.x. Click on the corresponding download button for your operating system (Windows, macOS, or Linux).
Once the download is complete, locate the downloaded file and run the installer.
Follow the installation wizard's instructions to install Node.js. You may be asked to accept the license agreement, choose the installation location, and select additional components to install (such as npm, the Node Package Manager).
After completing the installation, open your command prompt or terminal and type "node -v" to check if Node.js has been successfully installed. You should see the version number (e.g., v14.15.1) displayed in the output.
Additionally, you can also check if npm (Node Package Manager) has been installed by typing "npm -v" in the command prompt or terminal. This will display the version number of npm if it has been installed correctly.
Congratulations! You have successfully installed Node.js 14 on your system. You can now start using Node.js to develop applications, run scripts, and leverage the vast ecosystem of Node.js packages and libraries.
