Script Preparation code:

const useHandler = (handler) => React.useRef(handler).current;

function useHandlerComponent() {
    const testFunction = useHandler(evt => evt.preventDefault(), []);
    return React.createElement('button', {
        onClick: testFunction
    }, 'Test click');
}

function UseCallbackComponent() {
    const testFunction = React.useCallback(evt => evt.preventDefault(), []);
    return React.createElement('button', {
        onClick: testFunction
    }, 'Test click');
}

Tests:

ComponentWithOuterFunctionUseCallback
ReactDOM.render(React.createElement(useHandlerComponent), document.getElementById('root'))
ComponentWithUseCallback
ReactDOM.render(React.createElement(UseCallbackComponent), document.getElementById('root'))
