So is let in some languages. In Rust, you have to constantly opt out from immutability with let 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.
I think you can do
const thing = ... as constto lock down the mutation?So is
