AbortControllerintermediate

AbortController — signal.aborted stays true after multiple aborts

📖 Usage Example

const ac = new AbortController()
ac.signal.addEventListener('abort', () => console.log('aborted!'))
ac.abort()  // → logs 'aborted!'

Listen to the 'abort' event on signal to react when cancellation occurs.

AbortController multiple abort calls

signal.aborted remains true even if abort() is called multiple times.

Challenge: Call abort() twice and verify signal.aborted is still true.

💡 Hints (1)

• abort() is idempotent: calling it multiple times does not change the already-aborted state
