JAVASCRIPT

(0 , _reactRouterDom.useHistory) is not a function

You are using the beta version of react-router-dom. In v6, useHistory is 
replaced by useNavigate

If you want to use useHistory you should install v5 instead.

const navigate = useNavigate();

const onSavePostClicked = () => {
  if (name && description) {
    dispatch(todoUpdated({ id: todoId, name, description }));
    navigate(`/todo/${todoId}`);
  }
};
