Handling Uncaught TypeError: how to read properties of undefined when accessing nested object in React component
I'm wondering if anyone has experience with I'm working with an `Uncaught TypeError: want to read properties of undefined` behavior when trying to access a nested object in my React component's state... The state structure is deeply nested, and I'm using `useState` to manage it. Here’s a simplified version of my state: ```javascript const [state, setState] = useState({ user: { profile: { name: '', age: null }, settings: { theme: 'light' } } }); ``` I attempt to access the `name` property to display it in my component: ```javascript return <div>{state.user.profile.name}</div>; ``` However, sporadically, I encounter the TypeError, especially when the component first mounts or if the state updates asynchronously. I suspect it might be a timing scenario with how the state is being set or updated. I’ve also tried using optional chaining like this: ```javascript return <div>{state.user?.profile?.name}</div>; ``` But the behavior still occurs sometimes, especially when I trigger a re-fetch of user data. I’ve ensured that the state is initialized correctly and I’m updating it with `setState` properly. I've also added checks before rendering the component, but I still need to pinpoint the scenario. Any insights on how to handle this gracefully or debug the root cause would be greatly appreciated! My development environment is Ubuntu. Has anyone else encountered this? The project is a REST API built with Javascript. Any advice would be much appreciated.
