Web APIs (navigator, geolocation, history)

The History API enables manipulating browser session history within a page: 1) It allows web applications to add, modify, and remove entries in the browser's session history stack, 2) This enables changing the URL displayed in the address bar without triggering a full page reload, 3) It's a fundamental component of single-page applications (SPAs) that need to maintain distinct URLs for different views, 4) It supports proper back/forward button functionality in JavaScript-heavy applications, 5) It maintains the user's expectation that the browser's back button will navigate to the previous state, 6) It enables updating page metadata (title, URL) when content changes dynamically, 7) It preserves bookmarking capabilities even with dynamically generated content, 8) For privacy and security reasons, it only allows manipulation of history within the current origin, not across all visited sites.
