title: import { h } from preact - when is it necessary
body: <p>I'm currently building a Preact PWA with the CLI.</p>
  
  <p>My understanding was that wherever I have a component defined with JSX, I need to have <code>import { h } from 'preact'</code> at the top of the file.</p>
  
  <p>I removed all instances of that import statement, yet the application still runs and builds perfectly fine.</p>
  
  <p>Can someone set me straight here, as I'm a little confused now - perhaps there is some magic going on behind the scenes somewhere?</p>
