/**
 * <p>
 *             The <code>DeleteHIT</code> operation is used to delete HIT that is no longer needed.
 *             Only the Requester who created the HIT can delete it.
 *         </p>
 *         <p>
 *             You can only dispose of HITs that are in the <code>Reviewable</code> state,
 *             with all of their submitted assignments already either approved or rejected.
 *             If you call the DeleteHIT operation on a HIT that is not in the <code>Reviewable</code> state
 *             (for example, that has not expired, or still has active assignments),
 *             or on a HIT that is Reviewable but without all of its submitted assignments
 *             already approved or rejected, the service will return an error.
 *         </p>
 *         <note>
 *             <ul>
 *                <li>
 *                     <p>
 *                         HITs are automatically disposed of after 120 days.
 *                     </p>
 *                 </li>
 *                <li>
 *                     <p>
 *                         After you dispose of a HIT, you can no longer approve the HIT's rejected assignments.
 *                     </p>
 *                 </li>
 *                <li>
 *                     <p>
 *                         Disposed HITs are not returned in results for the ListHITs operation.
 *                     </p>
 *                 </li>
 *                <li>
 *                     <p>
 *                         Disposing HITs can improve the performance of operations such as ListReviewableHITs and ListHITs.
 *                     </p>
 *                 </li>

 * Use a bare-bones client and the command you need to make an API call.

 * // import type { MTurkClientConfig } from "@aws-sdk/client-mturk";
 * const config = {}; // type is MTurkClientConfig
 * const client = new MTurkClient(config);
 * const input = { // DeleteHITRequest
 *   HITId: "STRING_VALUE", // required
 * };
 * const command = new DeleteHITCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
