Constants

Constants protect specific data from unintended modification, allowing both the program and its dependents to rely on those values. Constants provide stability and predictability in a codebase. Once a value is assigned to a constant, it is fixed for the entire lifetime of the program. A constant is a programming construct that holds a value which cannot be altered by the program during execution. Modifying a constant-like value mid-execution would break all assumptions the rest of the program is built upon. Constants are appropriate whenever a value must serve as an unchangeable foundation for a program's logic.
