RELATES_TORootCause

console.log(person.id, "this should not run on every loop"); — const listItems = person.map((person) => (.

RELATES_TOProblem

"this should not run on every loop" — const listItems = person.map((person) => (. Tension: I tried memo and few other options but none worked. Outcome: You can separate the listItems to a new component and `useMemo` the url.

PERTAIN_TOProblem

The component throws `Rendered more hooks than during the previous render` when loading the page and after fetching additional users.

PERTAIN_TORootCause

`handleRender` is a new function on each `App` render, and so is `onRender` prop — `memo` can't prevent `ExpensiveComponent` from being re-rendered. Tension: `memo` can't prevent `ExpensiveComponent` from being re-rendered. Outcome: function reference stays the same through the component lifetime.

PERTAIN_TOProblem

These functions are get re-created, causing memoized children to re-render unnecessarily. — I have a dashboard with many components, and i try to pass functions as props to deeply nested children. Tension: Every time a parent re-renders, these functions are get re-created.

PERTAIN_TOSolution

`useCallback` needs to be used — to be used as a callback and thus prevent the unnecessary re-renders. Tension: `memo` can't prevent `ExpensiveComponent` from being re-rendered. Outcome: const handleRender = useCallback(() => {...}, []);.

PERTAIN_TOProblem

"this should not run on every loop" — const listItems = person.map((person) => (. Tension: I tried memo and few other options but none worked. Outcome: You can separate the listItems to a new component and `useMemo` the url.

PERTAIN_TOSolution

You can separate the listItems to a new component and `useMemo` the url — const ListItem = ({ person, removeThis }) => {. Outcome: const ListItem = ({ person, removeThis }) => { const src = useMemo(() => { console.log(person.id, "this should not run on every loop");.
