What is $t in Vue.js : <p>First time ever working with <code>Vue.js</code> and have no clue what is <code>$t</code>. For instance I have someone's code like this: </p>

<pre><code> &lt;li class="category-filter__back"&gt;
   &lt;button
     class="category-filter__button"
     @click="back(categoryPath)"&gt;
     {{ $t(backButtonText) }} &lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt; what is this $t?
   &lt;/button&gt;
 &lt;/li&gt;
</code></pre>

<p>Can't seem to find any concrete answer for this. </p>
