Unexpected array mutation during a while loop in React causing render issues
I've searched everywhere and can't find a clear answer. I'm working with a challenging scenario in my React application where I'm using a while loop to process an array of objects. The goal is to filter out certain items based on a condition, but it seems that the mutation within the loop is causing unexpected renders and state updates. I have the following code: ```javascript const MyComponent = () => { const [items, setItems] = useState([ { id: 1, value: 'A' }, { id: 2, value: 'B' }, { id: 3, value: 'C' } ]); const filterItems = () => { let tempItems = [...items]; let index = 0; while (index < tempItems.length) { if (tempItems[index].value === 'B') { tempItems.splice(index, 1); } else { index++; } } setItems(tempItems); }; useEffect(() => { filterItems(); }, []); return <div>{items.map(item => <p key={item.id}>{item.value}</p>)}</div>; }; ``` After calling `filterItems`, I get a warning about updating state on an unmounted component, which leads me to believe that the state update is being triggered multiple times. I am unsure if the scenario arises from the way I'm mutating `tempItems` or the while loop's logic. I tried replacing the while loop with a forEach loop, but that also led to similar issues. Has anyone encountered similar problems, or can you suggest a better approach to achieve this filtering without causing additional renders or errors? Am I missing something obvious?
