title: What is the real benefit of arrow functions although when they lack - this, arguments, new, super?
body: <p>Arrow functions:</p>
  
  <p>Do not have <code>this</code>.<br>
  Do not have <code>arguments</code>.<br>
  Can’t be called with <code>new</code>.</p>
  
  <p>(They also don’t have super, but we didn’t study it. Will be in the chapter Class inheritance, super).</p>
