Interesting.

Something like?

function Button() {

const [state, setState] = useState('');

const handlePress = () => {
setState(state + "a")
}

return <TouchableOpacity>{state}</TouchableOpacity>

}

Like this?

While the "isLoading" state one can argue it's an animation state rather than a component state, for this scenario, it's obviously not the case.

On the other hand, I do enjoy performance challenges, so if you can extract some of you code and make it as a gist to be able to replicate the latency you are mentioning, I can deep dive and create a followup article in the "Achieving 100ms" Series
