Línea de trabajo

Abre la página react.dev/learn/render-and-commit y revisa “Step 3: React commits changes to the DOM”, especialmente la frase sobre volver a renderizar con props diferentes y su playground. Compárala con la página enlazada “State as a Snapshot”, después actualiza la explicación para que la distinción quede clara y verifica la vista previa de la documentación y los enlaces.

Summary

Add an explanation text to avoid any confusion about the fact that it's the component's internal state changes, not the props themselves, that actually trigger the render (cf : the Big Re-renders Myth as mentioned by Nadia Makarevich).

Details

Section : "Step 3: React commits changes to the DOM"

In this section, there is a sentence which could create some confusion for a new React Developer.
Indeed, even if it is recalled various times in this page, this sentence could bring some confusion since it is not clearly established that a re-render is triggered by state changes instead of props. Therefore, I suggest to add some short explanations to explicitly clarify this distinction.
This is also a good way to create a common thread with the next page "State as a Snapshot".

Moreover, the playground doesn't help to understand this distinction since we don't use any useState hook in this component but in the parent component (we have to fork it to see all the components):

  • The original sentences :

React only changes the DOM nodes if there’s a difference between renders. For example, here is a component that re-renders with different props passed from its parent every second.

  • The additional sentence :
    It's worth noting that although props are updated, it's the component's internal state changes that actually trigger the render.
