Takeaways

• 😀 Node.js is a cross-platform runtime that works on Windows, macOS, and Linux, and in this video, the focus is on installation for macOS and Windows.
• 😀 To install Node.js, visit the official website (nodejs.org) and download the LTS (Long Term Support) version, which is the stable release most users should choose.
• 😀 For macOS, the installation process is simple, and it automatically installs both Node.js and npm (Node Package Manager).
• 😀 macOS users should ensure that the Node.js installation directory is added to the system's PATH to access it globally from any terminal session.
• 😀 On macOS, you can verify the installation by typing `node -v` in the terminal. If installed correctly, it shows the Node.js version number.
• 😀 In case of issues with the installation on macOS, check if the PATH is correctly set by using the `echo $PATH` command in the terminal.
• 😀 For Windows, it’s recommended to use Git Bash for terminal commands, as it supports Unix commands like `pwd` and `ls` that are compatible with macOS.
• 😀 After installing Node.js on Windows, you can verify the installation by opening Git Bash and running `node -v` to check the Node.js version.
• 😀 The Windows installation process is straightforward. After downloading the installer, follow the steps to accept the license and choose the installation directory.
• 😀 For both macOS and Windows, once Node.js is installed, it is ready to be used globally, and you can use `npm` for managing packages and dependencies.
