title: How to concatenate two variables and assign to the label attributes of lightning-card in lightning web component
body: <p>I have a lightning-card in lightning web component (LWC) and want to set the label attribute with two different variables. Although this can be done through the controller but I want to do this in html file itself.</p>
  
  <p>As in the code snippet, I am assigning {cardTitle} as a title, but I have another variable {totalCount} and want to concatenate the totalCount along with the cardTitle here. So lightning-card should have title like "{cardTitle}{totalCount}".</p>
  
  <pre><code>&lt;lightning-card title={cardTitle}&gt;&lt;/lightning-card&gt;
  
  //In Controler js
  @track cardTitle = 'Student details';
  @track totalCount = 0; //This will be set by the apex controller later and will have dynamic number
  </code></pre>
  
  <p>When I try below code</p>
  
  <pre><code>&lt;lightning-card title={cardTitle}{totalCount}&gt;&lt;/lightning-card&gt;
  </code></pre>
  
  <p>It shows error as </p>
  
  <blockquote>
    <p>multiple expressions found</p>
  </blockquote>
