Types of Modules in Node.js:

1. Core Modules/Internal packages : These are modules built into Node.js, so they can be used without installing anything.
2. Local Modules: Modules that you create for your own application, containing specific business logic or reusable code.
3. Third-Party Modules: These are external libraries that you can install via npm (Node Package Manager). They provide additional functionality, such as databases, authentication, utilities, and more.

1. Core Modules:

Node.js comes with several core modules that provide out-of-the-box functionality. Some common core modules include:

• fs: File system operations (reading, writing, manipulating files).
• http: Handling HTTP requests and creating web servers.
• path: Utilities for handling and transforming file paths.
• os: Information about the operating system.
• events: Working with event-driven programming and handling custom events.
• util: Utility functions (e.g., formatting, inspecting objects).
• crypto: Cryptographic functionalities for data encryption and decryption.
