Скачать или смотреть useImperativeHandle | React Hooks Tutorial #12

In this final episode of my React Hooks Tutorial, we will learn about the useImperativeHandle hook. In order to understand the useImperativeHandle hook, we first have to understand the concept of forwarding refs using the React.forwardRef function. This allows us to pass refs to nested components, because we cannot achieve so using the ref keyword. After that, we will make use of the useImperativeHandle hook inside an input to modify the forwarded ref by exposing a custom focusAndBlur property. The useImperativeHandle hook will allow us to call that method from the parent component using a button.
