我创建了一个Angular应用程序,可以从API中搜索学生.它工作正常但每次更改输入值时都会调用API.我做过一项研究,我需要一些叫debounce的东西,但我不知道如何在我的应用程序中实现它.

  <h1 class="mt-5 mb-5 text-center">Student</h1>
<div class="form-group">

        <th scope="col" class="text-center" style="width: 30%;">Name</th>
       <th scope="col" style="width: 30%;">E-mail</th>
        <th scope="col" style="width: 30%;">Phone</th> 
      </tr>
    </thead>
    <tbody>
      <tr *ngFor="let result of results">
        <th scope="row">{{result.stu_id}}</th>
        <td>{{result.stu_fname}} {{result.stu_lname}}</td>
         <td>{{result.stu_email}}</td>
        <td>{{result.stu_phonenumber}}</td> 
      </tr>
    </tbody>
  </table>
</div>
