State • Things have attributes and characteristics – Meeting is from 11am - 1pm on 3/6 in Fairfax – Car is blue and travelling north from Sunnyvale at 65 MPH • … whether they exist in the real-world, the computer, or both • … whether or not we observe or acknowledge them “State” (“data”) is a snapshot of those attributes & characteristics Best practice: Operate on state directly, not on dialogs about state
