What is the purpose of the process object in Node.js?

The process object is a global object that provides information about the current Node.js process. It can be used to interact with the environment, get command-line arguments, or manage process events. For example:

console.log(`Current directory: ${process.cwd()}`);
console.log(`Node version: ${process.version}`);
console.log(`Arguments: ${process.argv}`);
