In Node.js, there is no window or document object because Node.js operates in a server-side environment, not a browser environment.

Here's why these objects are absent:

Browser-Specific Objects:

  • The window object represents the browser window and provides a global context for JavaScript in the browser.It includes properties like document, alert, and others.

  • The document object represents the DOM (Document Object Model) of the webpage loaded in the browser.

Server-Side Nature of Node.js:

  • Node.js is designed for server-side applications, where its primary focus is on tasks like handling HTTP requests, reading/writing to the file system, working with databases, and performing backend logic.

  • These tasks don't require or involve rendering HTML or interacting with a graphical user interface (GUI), which is what window and document are meant for.

Global Context Differences:

  • In Node.js, the global context is represented by the global object, not window.

  • global provides access to built-in Node.js functionalities like process, Buffer, and others.

Use the Right Tools for the Job:

  • If you need to manipulate a DOM in Node.js, you can use libraries like jsdom to create a simulated DOM environment.

  • For server-side rendering of web pages, frameworks like Next.js or Express with templating engines are used.

If you need window or document in your project, it's likely you're dealing with front-end code and should use a browser environment or a framework like React, Angular, or Vue.

Thank You!
