API

combineAbortSignals(...signals: (AbortSignal | undefined)[]): AbortSignal

Creates a new AbortSignal that is aborted when any of the provided signals is aborted.

• Accepts undefined entries and ignores them.
• Aborts with the same reason as the first signal to abort.
• Useful for combining cancellation logic from multiple sources.
