react
Uncontrolled to controlled input switch
A component is changing an? uncontrolled input to be controlled
Fixes
- 1.Initialize state with an empty string instead of undefined: `useState('')` not `useState()`
- 2.Ensure the value prop is never undefined — use `value={val || ''}` as fallback
- 3.Decide on controlled or uncontrolled and stay consistent (use `defaultValue` for uncontrolled)
