 Watch methods are another superpower. Textual will call watch methods when reactive attributes are modified. Watch methods begin with `watch_` followed by the name of the attribute. If the watch method accepts a positional argument, it will be called with the new assigned value. If the watch method accepts *two* positional arguments, it will be called with both the *old* value and the *new* value.

 Compute methods are the final superpower offered by the `reactive` descriptor. Textual runs compute methods to calculate the value of a reactive attribute. Compute methods begin with `compute_` followed by the name of the reactive value.
 
-You could be forgiven in thinking this sounds a lot like Python's property decorator. The difference is that Textual will cache the value of compute methods, and update them when any other reactive attribute changes.
