<p>When the answer of Darin Dimitrov was posted back in 2010, the <code>maxlength</code> attribute wasn't implemented apparently. </p>

<p>Right know, in 2018, it is.</p>

<p><strong>Example</strong></p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">
  <label for="without">Without maxlength</label>
  <textarea id="without" class="form-control">
  

  With maxlength="10"
