ERROR ANALYSIS

Why am I getting 'Cannot read property of undefined'?

Classic one. This means you're trying to access a property on something that's `undefined`. **Most likely causes:** 1. **Async timing** — Data hasn't loaded yet ```js // user is undefined until fetch completes user.name // 💥 ``` 2. **Typo in property chain** ```js response.data.users // works response.data.user // undefined if typo response.data.user.name // 💥 ``` 3. **Optional property missing** ```js config.settings.theme // settings might not exist ``` **Quick fix:** Optional chaining ```js user?.name // returns undefined instead of crashing ``` Can you share the line that's erroring? I can pinpoint it.
