Vue internals have been rewritten into a assortment of decoupled modules, providing an architecture that delivers much better maintainability and lessened runtime measurement. Modules expose reduced-level APIs that unlock state-of-the-art use circumstances, these kinds of as the compiler supporting AST transforms for construct-time customizations.
