Let me ask you something: Could you try to name 2 or 3 good things about
const/immutable without looking it up? If not, you've really not
given enough
effort to learning about the benefits of it.
(1) Compiler helps you write correct multithreaded code
(2) You help compiler perform optimizations based on contracts
(3) I don't think there exists a #3 that's very different from #1 and #2
#3 Improves self-documentation of code - it's more understandable and
less susceptible to breakage during maintenance.
#4 Improves encapsulation
I'm not sure I would agree on this one. const/immutable arguably leak
implementation details more than they encapsulate them.
#5 Makes function purity possible
