Unless my memory is very hazy none of that is related to hooks. Identity in React has always relied on vDOM structure or `key` which was introduced in React 0.4.0 (July 17 2013, <2 months after initial public release). > For me, it's not OOP vs functional. Neither is for me. Note I didn't mention functional once. |

You are correct. But so, I believe, was I. Apologies for being unclear. vDOM structure is determined based on the return values from render functions. As opposed to the line of code where elements are created. So if you have `const cmp = <Comp />` in a render function, it doesn't have an identity yet. As you note, that will be determined later, sometime after this render function returns. It might not have a state at all. It might even have multiple states. If the current rendering is an update, `cmp` might be a mount instead.
All these determinations are made based on the content (structure and key attributes) of the assembled vDOM and the reconciliation heuristics.

I assumed that's the comparison you were drawing with this line. "better" than what?
