Overview

Node.js doesn’t have DOM APIs (no window or document), but it adds server APIs (file system, http).

Code Example

// Browser: window, document\n// Node: process, global, __dirname\nconsole.log(global);

Web Development Context

In modern web development, understanding Browser vs Node.js 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.
