How to use the @devexperts/remote-data-ts.isSuccess function in @devexperts/remote-data-ts

	switchMap(data => (isSuccess(data) ? f(data.value) : of(data)));

public render() {
		const { data } = this.props;
		return (
			
				{isPending(data) && this.renderPending()}
				{isSuccess(data) && this.renderSuccess(data.value)}
				{isFailure(data) && this.renderFailure(data.error)}
			
		);
	}

			switchMap(data => (isSuccess(data) ? this._getAllValues$ : of(data))),
			distinctUntilChanged(),

tap(value => {
				if (isSuccess(value)) {
					this.cache.set(key, value);
				}
			}),
		);

	tap(data => isSuccess(data) && f(data.value));

		map(data => data.filter(item => isSuccess(item))),
		map(array.sequence(remoteData)),

get(key: string, get: () => LiveData): LiveData {
		let sharedGetter: Observable> | undefined = this.cachedStreams.get(key);

		if (!isNotNullable(sharedGetter)) {
			const hasValue = this.cache.has(key);
			const cachedValue = this.cache.getValue(key);
			const valueIsResolved = isNotNullable(cachedValue) && isSuccess(cachedValue);
			if (hasValue && valueIsResolved) {
				return this.cache.get(key);
			}

			sharedGetter = new Observable>(observer => {
				const getterSubscription = get().subscribe(value => {
					this.cache.set(key, value);
				});

				const cacheSubscription = this.cache.get(key).subscribe(value => {
					observer.next(value);
				});

				return () => {
					getterSubscription.unsubscribe();
					cacheSubscription.unsubscribe();
