<h1>Example with text check</h1>

<p>In this example 'v-if' uses a method 'includes()' instead of a comparison operator.</p>

<p>Remove 'pizza' from the 'text' property inside the Vue instance, click 'Run' and see what happens.</p>

<div id="app">
  <div v-if="text.includes('pizza')">
    <p>The text includes the word 'pizza'</p>
    <img src="img_pizza.svg">
  </div>
  <p v-else>The word 'pizza' is not found in the text</p>
</div>
