title: What 'type' is the event for a change handler in TypeScript?
body: <p>I am fairly new to TypeScript and have just created a change handler function to take in the event as the parameter to set the value, i.e. <code>event.target.value</code>. I have currently set this to <em>any</em> but thinking there must be a correct type for this?</p>
  <p>This is my method which is within a functional react component:</p>
  <pre><code>const handleChange = (event: any) =&gt; {
    setValue(event.target.value);
  };
  </code></pre>
