Quote of the Week

In many cases, it is possible to completely rearchitect the underlying code while leaving the public API as-is, and without introducing new bugs. I've literally never had such a liberating experience with refactoring until Rust. In other words, I have never been so productive in any other language. Dynamic languages like JavaScript and Python are the least productive by far. Code runs, tests pass, put it into production and... uncaught exception! Time to rollback and redo that whole dance AGAIN. With Rust, we take care of all of that crap while actually writing the code the first time. No more surprise 3am wake up calls. That is productivity.

– Jay Oster on rust-users
