A variable is a named container for a value. Action parameters accept variables or hard-coded values.
A variable has several advantages over a hard-coded value:
- It has a name that makes its value more meaningful (e.g., maxNumberOfLives instead of 99).
- The same variable can be used in multiple places. Hard-coded values have to be edited separately.
- A variable's value can change over time!
