Prepack is a build-time transformation tool and static analysis engine designed to optimize JavaScript source code. By executing code during the build process, it evaluates program logic and state to precompute results, effectively simplifying complex operations before the application is deployed. The tool functions as a bundle optimizer that integrates into existing development pipelines to refine application logic. It employs abstract interpretation and symbolic execution to track program behavior across various paths, allowing it to perform constant folding, eliminate unreachable code, and

WebKit is a web browser engine used to build the core rendering and layout systems required to display web content. It provides the primary logic necessary to power fully functional web browsers and embedded web views. The project enables the rendering of web pages by processing HTML and CSS standards. It focuses on cross-platform support for macOS, iOS, and Linux environments, and allows for the integration of web browser windows within native applications. The engine handles JavaScript execution through optimization and tiered compilation. It manages the visual lifecycle of a page via a tr
