Web Development Context

In modern web development, understanding Process Management (PM2) is crucial. Node.js is widely used for building APIs, real-time applications, and microservices. Mastery of this concept allows you to build efficient, scalable, and secure backend systems.

Common Mistakes

• Blocking the event loop with heavy synchronous tasks.
• Exposing secrets in code instead of environment variables.
• Forgetting to handle promise rejections.
