pattern ~ a solution applied more than once to a problem scenario when it occurs in a particular context
Types of design patterns (for software development)
- creational pattern
  
  pattern that helps with the creation of an instance of an object
- structural pattern
  
  pattern that helps with the setup of communication pathwayw between different groups of objects
- behavioral pattern
  
  pattern that helps with the partitioning of system behaviors into discrete classes
command (in software development) ~ an object whose job is to store all the information needed to execute a particular action. See https://www.baeldung.com/java-command-pattern.
Command pattern ~ an interface, typically named Command, with a single method, typically named Execute.
