What is process in Node.js?

Short answer: process is a global object that provides information and control over the current Node.js process. 📌 Examples: console.log(process.pid); // Process ID console.log(process.platform); // OS platform You can also handle exit events: process.on('exit', () => { console.log('Exiting...'); });
