                           UNDERSTANDING VARIABLES

                 A variable is a storage unit that holds data. In App Lab, variables are used to store user
                 input, numbers, or text. A variable's value can be updated at any time, allowing dynamic
                 changes in the program. Variables help manage data, perform calculations, and track
                 user interactions.
