WebKit
WebKit is an open-source web browser engine primarily used by Safari, Mail, and other Apple applications to render web content. It parses HTML, CSS, and JavaScript to display web pages, and includes components like WebCore for layout and JavaScriptCore for script execution. Originally derived from KHTML, it has evolved into a key technology powering many browsers and applications across various platforms.
Developers should learn WebKit when building or optimizing web applications for Apple ecosystems, such as Safari on iOS and macOS, to ensure compatibility and performance. It's also valuable for creating cross-platform web views in native apps using frameworks like WKWebView, and for contributing to browser engine development or debugging web rendering issues specific to WebKit-based browsers.
