## Deferred<T>

> Work in progress

Deferred provides an object to manage promises.

```typescript
class Sample<T> {
    private readonly _deferred = new Deferred<T>();

    /* Method called during the application load once the authentication token is available */
    setToken(value: T): void {
        this._deferred.resolve(value);
    }

    /* Method called at any time that will be blocked until the token is set */
    async fetchData(): Promise<Response> {
        const token = await this._deferred;
        return fetch("/data/", { headers: { Authorization: `bearer ${token}` } });
    }
}
```
