Explain in your own words the process of creating and updating a variable. How does the Counter Pattern with Event work?

Variables are created when a value is given a preferred name of choice.

Updated myvalue variable may look like ; myvalue = [2,3,5]Counters are used to track the number of times a certain process is performed. Counters are usually set to increase each time a task is performed. Counter =0;after every process; counter =+1
