### Executing Guards
To execute a guard or a set of guards against data, you use the `executeGuardWithData` method for a single guard, or `executeGuardsWithData` method for a `GuardSet`.
To execute a guard or a set of guards against data, you use the `execGuardWithData` method for a single guard, or `execGuardsWithData` method for a `GuardSet`.

In this example, we create a `MinLengthGuard` class that extends `Guard` and validates a string based on its minimum length.
### Conclusion
`@push.rocks/smartguard` provides a powerful framework for creating and managing validation guards in JavaScript and TypeScript applications. The library's flexibility allows it to handle simple boolean checks, asynchronous operations, integration with external APIs, and complex composite validations. Its use of `Guard` and `GuardSet` classes ensures that validations are both modular and reusable.
Whether you are validating form inputs, securing APIs, or ensuring data integrity in your backend services, `@push.rocks/smartguard` simplifies the process and makes your code cleaner and more maintainable.
