Exercise - Finalize Operator
Exercise
- Open exercise on codesandbox.
This exercise builds on the previous exercise using the
catchError() operator.
Note that I've added a new message constant variable that is a reference to an HTMLDivElement that displays an error message.
By default, the div element is hidden using the hidden class on the element.
In the catchError() method I have removed the hidden class.
- Your task is to use the
finalize() operator to add the hidden class back to the div element after 5000 milliseconds.
