function ComponentWithUseCallback() {
  const testFunction = React.useCallback(evt => evt.preventDefault(), []);
  return React.createElement('button', {onClick: testFunction}, 'Test click');
}


function ComponentWithoutUseCallback() {
  const testFunction = evt => evt.preventDefault();
  return React.createElement('button', {onClick: testFunction}, 'Test click');
}

Tests:

without
ReactDOM.render(React.createElement(ComponentWithUseCallback), document.getElementById('root'))
usecallback
ReactDOM.render(React.createElement(ComponentWithoutUseCallback), document.getElementById('root'))
