Beyond JSX: Rethinking the Component Model in Frontend

Beyond JSX examines how traditional component models struggle with increasing application complexity. Components have grown from simple UI units to complex mini-apps handling multiple concerns, leading to fragility and performance issues. Modern frameworks are separating UI structure from business logic, using fine-grained reactivity instead of full function re-renders, and moving away from deeply nested component trees. While JSX syntax remains valuable, frameworks like Marko, Qwik, SolidJS, and Svelte showcase alternative execution models that treat JSX as a description rather than a process, improving efficiency and performance.
