The Variable as Name-Value Pair
Captions available
The idea
A variable is a container holding a value — a name-value pair, with primitive types storing the actual value directly at the named memory location.
In practice
A balance named in a ledger app is one name bound to one stored number.
Where people slip
The direct-storage picture holds for primitives only.
