8 months ago - How to add a ref to your component?
- To add a ref to your component in React, you can use useRef.
- How to update a ref’s value?
- Refs should not be updated directly. Instead, you can use the current property of the ref to change its value.
- How refs are different from state?
- Refs and state are both ways to store and track information, but they serve different purposes.
- Refs are often used to access DOM elements or to track values that don't cause a re-render.
- In contrast, state is used to store values that can change and trigger a re-render when they do.
- How to use refs safely?
- When using refs, ensure that you use them safely and avoid updating them directly.
- Typically, refs are used to reference DOM elements, and instead of changing the value directly, you should use setState to update the state and trigger a re-render.
- Use refs cautiously to avoid conflicts with how React manages and updates state.
