Constants are variables whose value does not change during the runtime of a program after initialization. Oftentimes, constants are used in
multiple locations across different subroutines.
It is important that the names of constants follow a consistent and easily recognizable pattern. This way, readers immediately understand that the
referenced value does not change, which simplifies debugging.
Or, in the case of primitive constants, that accessing the constant is thread-safe.
This rule checks that all constant names match a given regular expression.
What is the potential impact?
Ignoring the naming convention for constants makes the code less readable since constants and variables are harder to tell apart. Code that is hard
to understand is also difficult to maintain between different team members.
