Installing Node.js and npm

Node.js is a runtime environment that allows you to run JavaScript on the server side, and npm (Node Package Manager) is a tool that helps you manage and install packages (libraries and frameworks) for your Node.js projects.

Here's how you can install Node.js and npm on your system:

1. Download Node.js: Go to the official Node.js website at https://nodejs.org/. On the homepage, you'll see two versions to choose from: LTS (Long-Term Support) and Current. For most users, it's recommended to download the LTS version, as it's more stable and suitable for production use.
2. Choose Your Operating System: Select the appropriate version for your operating system (Windows, macOS, or Linux). Node.js provides installers for each platform.

3. Install Node.js and npm:

   • Windows: Download the Windows Installer (.msi) from the Node.js website. Run the installer and follow the installation instructions. This will install both Node.js and npm.
   • macOS: Download the macOS Installer (.pkg) from the Node.js website. Run the installer and follow the installation instructions. This will install both Node.js and npm.
   • Linux: The process might vary slightly depending on your Linux distribution. One common method is to use the package manager that comes with your distribution. For example, on Debian-based systems (such as Ubuntu), you can use the following commands in the terminal:
     bash

     sudo apt update sudo apt install nodejs npm

4. Verify Installation: After installation, you can verify that Node.js and npm are installed by opening a terminal and typing the following commands:

   bash

   node -v npm -v

   These commands will display the installed versions of Node.js and npm, respectively.

Once you've completed these steps, you'll have Node.js and npm installed on your system. You can now start using Node.js to run JavaScript applications and npm to manage packages for your projects.

Remember that newer versions of Node.js and npm might be available after my last knowledge update in September 2021. Always refer to the official Node.js website for the latest information and installation instructions.
