Installing Node.js and npm

Node.js comes bundled with npm, so installing Node.js will also install npm. Here's how you can do it:

For macOS users, you can use Homebrew:

brew install node

For Windows users, download the LTS version from the official Node.js website and follow the installation instructions.
