The browser context refers to the overall environment and capabilities provided by the web browser to web applications. It contains many things inside itself, like the window object, DOM, and Browser APIs.
Window Object: In JavaScript, the window object is the main entry point to the browser context. We can access the window object and its properties and methods to interact with the browser. For example:- window.alert("Hello world!").

Document Object Model (DOM): The DOM is the way the browser represents the structure of the web page. JavaScript can use the DOM to access and manipulate the elements on the page.

Browser APIs: Browsers provide various APIs that JavaScript can use to extend the functionality of web applications.
