Added Topics: JavaScript Window Object & History Object

[deepanshu-prajapati01]

Hi team 👋

This PR introduces two new topics focused on the JavaScript Window and History objects, providing detailed explanations and practical examples about browser window manipulation and session navigation.

---

🔍 Problem Resolved

• There was no dedicated coverage on the Window object, which represents the browser window and exposes numerous properties and methods.
• The History object, which allows programmatic control over the browser session history, was undocumented.

---

✅ What’s Changed

• Added a "JS Window Object" topic explaining:

  • The Window object as the global object in browsers.
  • Common properties (location, document, navigator, screen, etc.).
  • Useful methods like alert(), open(), close(), focus(), setTimeout(), and others.
  • Examples demonstrating interaction with the browser window and environment.

• Added a "JS History Object" topic covering:

  • The History interface and its use for managing session history.
  • Methods like back(), forward(), go(), pushState(), and replaceState().
  • Practical usage for SPA navigation and state management.
