The main big feature that comes with React 19 is that it will now have is own <a href="https://react.dev/learn/react-compiler#what-does-the-compiler-do" rel="noopener noreferrer">compiler</a>:</p> <blockquote> <p>In order to optimize applications, React Compiler automatically<br> memoizes your code. You may be familiar today with memoization through<br> APIs such as <code>useMemo</code>, <code>useCallback</code>, and <code>React.memo</code>. With these APIs you<br> can tell React that certain parts of your application don’t need to<br> recompute if their inputs haven’t changed, reducing work on updates.</p> </blockquote> <p>Does this means that Million.js will become obsolete with React 19?</p>
