How would you install and set up Lua on a computer? Provide step-by-step instructions for Windows and macOS.

To install and set up Lua on a computer, the steps may vary slightly depending on the operating system. Here are step-by-step instructions for installing and setting up Lua on both Windows and macOS:

For Windows:

1. Visit the LuaBinaries website (<https://luabinaries.net/>) in your web browser.
2. Under the "Download" section, locate the "Windows Binaries" category.
3. Choose the appropriate version of Lua based on your system architecture (32-bit or 64-bit). Typically, it is recommended to select the latest stable version available.
4. Click on the download link next to the selected version to start downloading the Lua binaries for Windows.
5. Once the download is complete, locate the downloaded file and double-click on it to run the installer.
6. Follow the on-screen instructions provided by the installer. By default, the installer will suggest installing Lua to the "C:\Program Files (x86)\Lua" directory. You can choose a different location if desired.
7. During the installation, ensure that the "Add Lua to the PATH" option is selected. This will allow you to run Lua from any command prompt window without specifying the full path.
8. Complete the installation process by clicking "Next" or "Finish" when prompted.
9. To verify the installation, open the Command Prompt by pressing the Windows key, typing "cmd," and selecting the "Command Prompt" application.
10. In the Command Prompt window, type "lua -v" and press Enter. If Lua is correctly installed, it will display the installed version information.

For macOS:

1. Open a web browser and visit the Lua website (<https://www.lua.org/>) or the LuaBinaries website (<https://luabinaries.net/>).
2. On the LuaBinaries website, locate the "macOS Binaries" category under the "Download" section.
3. Choose the appropriate version of Lua based on your macOS version. Typically, it is recommended to select the latest stable version available.
4. Click on the download link next to the selected version to start downloading the Lua binaries for macOS.
5. Once the download is complete, locate the downloaded file (usually a .pkg file) and double-click on it to run the installer.
6. Follow the on-screen instructions provided by the installer to complete the installation process. The installer will guide you through selecting the installation location and other preferences.
7. After the installation is finished, open the Terminal application on your macOS. You can find it in the "Utilities" folder within the "Applications" folder.
8. In the Terminal window, type "lua -v" and press Enter. If Lua is correctly installed, it will display the installed version information.

Following these steps will ensure that Lua is properly installed and set up on your Windows or macOS computer. Once installed, you can start writing Lua scripts and executing them from the command prompt or terminal.
