Pick a task and watch a sample answer stream in. Open the same prompt in Chatday when you’re ready.

Why does this return undefined? const u = users.find(u => u.id = id)

The bug is in the arrow body: u.id = id assigns instead of compares, so the callback returns the assigned value and .find never matches the way you expect.

Fix it with a strict comparison:

const u = users.find(u => u.id === id);

Use === to compare. A single = is assignment, which is why you saw undefined.
