AbortController: Cancel In-Flight Web Requests
AbortController is a remote kill switch for web requests. You create a controller, pass its `signal` to a `fetch` call, and can then call `abort()` to cancel it. Use it to stop requests when a user navigates away. The footgun is forgetting this signal.
AbortController provides a standard way to cancel asynchronous tasks like `fetch`. Think of it as a remote kill switch: create a controller, pass its `signal` to the request, and call `abort()` to terminate it. This is essential for cleaning up effects in UI components, like cancelling searches in a type-ahead input when the user types again. A common mistake is forgetting to pass the `signal` to the `fetch` options; without it, calling `abort()` does nothing.
