 <ul>
 <li>Fast Refresh preserves React local state in function components (and Hooks) by default.</li>
 <li>Sometimes you might want to <em>force</em> the state to be reset, and a component to be remounted. For example, this can be handy if you're tweaking an animation that only happens on mount. To do this, you can add <code>// @refresh reset</code> anywhere in the file you're editing. This directive is local to the file, and instructs Fast Refresh to remount components defined in that file on every edit.</li>
-<li>You can put <code>console.log</code> or <code>debugger;</code> into the components you edit during a Fast Refresh session.</li>
 </ul>

+<p>When possible, Fast Refresh attempts to preserve the state of your component between edits. In particular, <code>useState</code> and <code>useRef</code> preserve their previous values as long as you don't change their arguments or the order of the Hook calls.</p>
+<p>Hooks with dependencies—such as <code>useEffect</code>, <code>useMemo</code>, and <code>useCallback</code>—will <em>always</em> update during Fast Refresh. Their list of dependencies will be ignored while Fast Refresh is happening.</p>
+<p>For example, when you edit <code>useMemo(() =&gt; x * 2, [x])</code> to <code>useMemo(() =&gt; x * 10, [x])</code>, it will re-run even though <code>x</code> (the dependency) has not changed. If React didn't do that, your edit wouldn't reflect on the screen!</p>
+<p>Sometimes, this can lead to unexpected results. For example, even a <code>useEffect</code> with an empty array of dependencies would still re-run once during Fast Refresh. However, writing code resilient to an occasional re-running of <code>useEffect</code> is a good practice even without Fast Refresh. This makes it easier for you to later introduce new dependencies to it.</p>
