+/**
+ * When the passed timespan elapses before the source emits any given value, it will unsubscribe from the source,
+ * and switch the subscription to another observable.
+ *
+ * <span class="informal">Used to switch to a different observable if your source is being slow.</span>
+ *
+ * Useful in cases where:
+ *
+ * - You want to switch to a different source that may be faster.
+ * - You want to notify a user that the data stream is slow.
+ * - You want to emit a custom error rather than the {@link TimeoutError} emitted
+ *   by the default usage of {@link timeout}.
+ *
+ * If the first parameter is passed as Date and the time of the Date arrives before the first value arrives from the source,
+ * it will unsubscribe from the source and switch the subscription to another observable.
+ *
+ * <span class="informal">Use Date object to switch to a different observable if the first value doesn't arrive by a specific time.</span>
+ *
+ * Can be used to set a timeout only for the first value, however it's recommended to use the {@link timeout} operator with
+ * the `first` configuration to get the same effect.
+ *
+ * ## Examples
+ *
+ * Fallback to a faster observable
+ *
+ * ```ts
+ * import { interval, timeoutWith } from 'rxjs';
+ *
+ * const slow$ = interval(1000);
+ * const faster$ = interval(500);
+ *
+ * slow$
+ *   .pipe(timeoutWith(900, faster$))
+ *   .subscribe(console.log);
+ * ```
+ *
+ * Emit your own custom timeout error
+ *
+ * ```ts
+ * import { interval, timeoutWith, throwError } from 'rxjs';
+ *
+ * class CustomTimeoutError extends Error {
+ *   constructor() {
+ *     super('It was too slow');
+ *     this.name = 'CustomTimeoutError';
+ *   }
+ * }
+ *
+ * const slow$ = interval(1000);
+ *
+ * slow$
+ *   .pipe(timeoutWith(900, throwError(() => new CustomTimeoutError())))
+ *   .subscribe({
+ *     error: err => console.error(err.message)
+ *   });
+ * ```
+ *
+ * @see {@link timeout}
+ *
+ * @param due When passed a number, used as the time (in milliseconds) allowed between each value from the source before timeout
+ * is triggered. When passed a Date, used as the exact time at which the timeout will be triggered if the first value does not arrive.
+ * @param withObservable The observable to switch to when timeout occurs.
+ * @param scheduler The scheduler to use with time-related operations within this operator. Defaults to {@link asyncScheduler}
+ * @return A function that returns an Observable that mirrors behaviour of the
+ * source Observable, unless timeout happens when it starts emitting values
+ * from the `ObservableInput` passed as a second parameter.
+ * @deprecated Replaced with {@link timeout}. Instead of `timeoutWith(100, a$, scheduler)`, use {@link timeout} with the configuration
+ * object: `timeout({ each: 100, with: () => a$, scheduler })`. Instead of `timeoutWith(someDate, a$, scheduler)`, use {@link timeout}
+ * with the configuration object: `timeout({ first: someDate, with: () => a$, scheduler })`. Will be removed in v8.
