# Utilities & Libraries

The Miru Javascript runtime provides several built-in utilities and standard libraries.

## Networking

### `fetch()`
Modern standard for network requests. Fully supported and recommended.
```javascript
const res = await fetch("https://example.com");
```

### `Miru` object (Legacy)
- `Miru.request(url)`: Uses `@webSite` as base.
- `Miru.rawRequest(url)`: Absolute URL request.

## Built-in Modules
Import these using `require()`:

- **`linkedom`**: HTML/XML DOM Parser.
- **`crypto-js`**: Cryptographic algorithms (AES, SHA, etc.).
- **`md5`**: MD5 hashing.
- **`jsencrypt`**: RSA encryption.
- **`url`**: URL parsing and resolution.

## UI Utilities
- **`throwError(message)`**: Halts execution and displays an error message to the user.
