[Suggestion]: Providing formal definition of equality of two JSX values or giving a clarity if there is no formal definition possible.

Summary

Details

React documentation on "Keeping Components Pure" says that

React assumes that every component you write is a pure function. This means that React components you write must always return the same JSX given the same inputs.

It also mentions:

React offers a “Strict Mode” in which it calls each component’s function twice during development. By calling the component functions twice, Strict Mode helps find components that break these rules.

However, the page does not provide a formal definition of what it means for two JSX values to be "equal."

we can easily say 4 === 4 or "foo" === "foo",
But, To give a simple example, how do we define the equality of two JSX values like: "<Child {childConfig}="object1"> and <Child {childConfig}="object2">"

If object1 and object2 are deeply equal, does that imply that both JSX elements are considered equal as well? Or is equality based on referential identity of object1 and object2?
I think, This distinction is important to understand what it truly means of two JSX values being same.

If such a definition exists elsewhere in the React documentation, it would be helpful to reference it explicitly from this page to clarify expectations around JSX equality and purity.

Inizia dalla pagina “Keeping Components Pure” collegata nell’issue e rivedi la sua spiegazione degli input uguali e dei risultati JSX. Chiarisci se l’uguaglianza di JSX debba essere definita formalmente o sostituita da indicazioni pratiche sull’identità degli oggetti e sull’uguaglianza profonda, e aggiungi un riferimento o una spiegazione esplicita affinché i lettori sappiano che cosa significa “lo stesso JSX”.
