 # Disable Default Validation
 
-👨‍💼 Now that we have nice looking error messages we manage ourselves, we want to
-disable the built-in browser errors because they go counter to our design
-aesthetic.
+👨‍💼 Super! Now we can rest assured that the built-in client validation will still
+apply until our JavaScript shows up to make things even better!
 
-But we don't want to disable them completely, just once our JavaScript has
-loaded to enhance the user experience. Until that time, the browser's built-in
-client-side validation is ok. So, we'll use a little trick to disable them only
-after our React app has hydrated:
-
-```tsx
-function useHydrated() {
-	const [hydrated, setHydrated] = useState(false)
-	useEffect(() => setHydrated(true), [])
-	return hydrated
-}
-```
-
-We effectively only need to assign the return value of that hook to the
-`noValidate` prop of our form and we're good to go.
+But... our JavaScript isn't making things much better on the client just yet...
+So let's handle that next!
