Because sometimes that
letcan be replaced by other things likeconst. Which can be managed statically by the machine and not by my (imperfect) ability to know if it's mutated or notI think you can do
const thing = ... as constto lock down the mutation?So is
letin some languages. In Rust, you have to constantly opt out from immutability withlet mut, which makes writing more procedural code feel like you're fighting with the compiler, and otherwise I don't really see the rationale behind full functional coding. I only had a bug caused only once by unwanted mutation, the hardest part fixing it was to learn the proper use of my debugger tool.
