Utility functions to use and combine `AbortSignal` and `AbortController` with Promises

export function mergeSignals(...signals) {
    const controller = new AbortController();
    for (const abort of signals) {
        const signal = abort instanceof AbortController ? abort.signal : abort;
        if (signal?.aborted) {
            controller.abort(signal.reason);
            return controller.signal;
        }
        signal?.addEventListener('abort', () => {
            controller.abort(signal.reason);
        }, { once: true });
    }
    return controller.signal;
}
