### Gorse TypeScript SDK Usage Example

Source: https://gorse.io/docs/0.4/api/typescript-sdk

Demonstrates how to create a Gorse client instance with an endpoint and API key, insert feedback data, and request recommendations. It showcases the core functionalities of the SDK.

```typescript
import { Gorse } from "gorsejs";

// Create the client.
const client = new Gorse({ endpoint: "http://127.0.0.1:8087", secret: "api_key" });

// Insert feedbacks.
await client.insertFeedbacks([
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'vuejs:vue', Timestamp: '2022-02-24' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'd3:d3', Timestamp: '2022-02-25' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'dogfalo:materialize', Timestamp: '2022-02-26' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'mozilla:pdf.js', Timestamp: '2022-02-27' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'moment:moment', Timestamp: '2022-02-28' }

// Create the client.
const client = new Gorse({ endpoint: "http://127.0.0.1:8087", secret: "api_key" });

// Insert feedbacks.
await client.insertFeedbacks([
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'vuejs:vue', Timestamp: '2022-02-24' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'd3:d3', Timestamp: '2022-02-25' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'dogfalo:materialize', Timestamp: '2022-02-26' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'mozilla:pdf.js', Timestamp: '2022-02-27' },
    { FeedbackType: 'star', UserId: 'bob', ItemId: 'moment:moment', Timestamp: '2022-02-28' }

public class Main {

    public static void main(String[] args) {
        // Create a client.
        Gorse client = new Gorse("http://127.0.0.1:8087", "api_key");

        // Insert feedback.
        List<Feedback> feedbacks = List.of(
                new Feedback("read", "100", "300", "2022-11-20T13:55:27Z"),
                new Feedback("read", "100", "400", "2022-11-20T13:55:27Z")
        );
        client.insertFeedback(feedbacks);

        // Get recommendation.
        client.getRecommend("100");
    }
}
```

$client = new Gorse("http://127.0.0.1:8087/", "api_key");

$rowsAffected = $client->insertFeedback([
    new Feedback("star", "bob", "vuejs:vue", "2022-02-24"),
    new Feedback("star", "bob", "d3:d3", "2022-02-25"),
    new Feedback("star", "bob", "dogfalo:materialize", "2022-02-26"),
    new Feedback("star", "bob", "mozilla:pdf.js", "2022-02-27"),
