title: Vue.js - Add Class on Click Event
body: <p>I would like to dynamically toggle a class on a <code>click</code> event on a div in Vue.js without using properties/data to do so.</p>
  
  <p>Here is my div</p>
  
  <p><code>&lt;div class="quiz-item" @click="checkAnswer(1)"&gt;</code></p>
  
  <p>When this <code>div</code> is clicked, I would like to add the class <code>quiz-item--correct</code> or <code>quiz-item--incorrect</code> (the logic for this will be handled elsewhere). I cannot use properties as there are too many answers in the quiz for it to be a maintainable/viable approach.</p>
  
  <p>Does anyone have any ideas on how I can achieve this functionality?</p>
