cross-spawn is a Node.js package that provides a consistent way to spawn child processes across different operating systems. It normalizes arguments and handles platform-specific differences, ensuring consistent behavior for running executables regardless of whether the user is on Windows, macOS, or Linux. By abstracting away OS intricacies, cross-spawn simplifies cross-platform development and reduces the likelihood of unexpected errors when spawning processes in Node.js applications. It's a dependency for many popular npm packages due to its reliability.
