Unexpected Array Output When Using Filter and Map Together in React - Key solution with State Updates
I've searched everywhere and can't find a clear answer. Quick question that's been bugging me - I'm working on a React application where I'm trying to filter and then map over an array of objects to render a list. However, the output is not what I expect, and I suspect it has to do with how I'm handling state updates. I'm using React 18 and my initial array is defined in the state as follows: ```javascript const [items, setItems] = useState([ { id: 1, name: 'Item 1', active: true }, { id: 2, name: 'Item 2', active: false }, { id: 3, name: 'Item 3', active: true } ]); ``` I filter the array based on the `active` property and then map over the results to generate a list: ```javascript const handleActiveItems = () => { return items .filter(item => item.active) .map(item => <li key={item.id}>{item.name}</li>); }; ``` However, when I render this in my component like so: ```javascript <ul>{handleActiveItems()}</ul> ``` it shows all items instead of just the active ones. Additionally, I've tried adding a console log to see the filtered array: ```javascript console.log(items.filter(item => item.active)); ``` This correctly logs the active items to the console. I've also checked if there's a state scenario, and I can confirm that the `items` state is not being mutated unintentionally elsewhere in my code. I’m not getting any errors in the console, but I am confused about how the output doesn’t match the filter criteria. Is there something I'm missing in terms of React state handling or lifecycle that could cause this behavior? Any insights would be greatly appreciated! My development environment is macOS. I'd really appreciate any guidance on this.
