Key Updates in React 19
React 19 introduces several significant upgrades aimed at enhancing developer experience, particularly focused on forms. A standout feature is the introduction of React Actions, which streamlines how forms are handled by allowing developers to link actions directly to form elements, eliminating the need for tedious onClick or handle submit event callbacks. React 19 also introduces new hooks like use action state and use form status, which aid in managing form state and processing without boilerplate code. Moreover, developers can rejoice as forward refs are no longer necessary, simplifying component ref management.
