The compiler (or in reality the borrow checker) is strict but once the program does compile, it usually is more defect free (even functionally) than one written in other languages. After a few months writing Rust, I recently had to go back and use Javascript for another project (I know drastically different worlds) and my own code gave me micro panic attacks thinking about all the ways that things can go wrong in it (I guess I'll probably end up using typescript instead in future).

Overall well worth the time spent learning Rust as I feel it makes me a better programmer overall enforcing the thinking about lifetimes, return values, shared data and thread safety.
