Custom useRef hook
livecode
Task condition
Create your own implementation of the useRef hook, mimicking its behavior in React. You need to write a function that returns an object with a current field, allowing you to store a mutable value between renders without recalculating it. When the hook is called, a stable object reference should be maintained throughout the component's lifecycle.
Requirements:
- The function should work without using the built-in
useReffrom the React library. - The returned object should have a
currentproperty that can be read and modified. - On subsequent calls within the same component, the reference to the object should remain unchanged.
- The implementation can be tested in a simple functional component, verifying that the value persists between renders.
Example usage (for illustration, code should not be changed):
function MyComponent() {
const ref = useMyRef(0);
// ...
}
