 However, when a component is unmounting, effect *cleanup* functions used to run synchronously (similar to `componentWillUnmount` being synchronous in classes). We've found that this is not ideal for larger apps because it slows down large screen transitions (e.g. switching tabs).
 
-**In React 17, the effect cleanup function will always runs asynchronously -- for example, if the component is unmounting, the cleanup will run _after_ the screen has been updated.**

 This mirrors how the effects themselves run more closely. In the rare cases where you might want to rely on the synchronous execution, you can switch to `useLayoutEffect` instead.

 * There are some [performance improvements and simplifications](https://github.com/reactjs/rfcs/blob/createlement-rfc/text/0000-create-element-changes.md#motivation) that `React.createElement` does not allow.
 
 To solve these issues, React 17 introduces two new entry points to the React package that are intended to only be used by compilers like Babel and TypeScript. Instead of transforming JSX to `React.createElement`, **the new JSX transform** automatically imports special functions from those new entry points in the React package and calls them.

 También tratamos de dar un extra para proveer advertencias útiles a los desarrolladores. Por ejemplo, React te advierte en desarrollo si anidas etiquetas de una forma que el navegador no las entiende, o si cometes un error de transcripción en la API. Las advertencias a desarrolladores y los chequeos relacionados son la razón principal por la que la versión de desarrollo de React es más lenta que la versión de producción.
