title: What do multiple arrow functions mean in JavaScript?
body: <p>I have been reading a bunch of <a href="https://en.wikipedia.org/wiki/React_(web_framework)" rel="noreferrer">React</a> code and I see stuff like this that I don't understand:</p>
  <pre><code>handleChange = field =&gt; e =&gt; {
    e.preventDefault();
    /// Do something here
  }
  </code></pre>
