Ok, for some perspective here, that 45 seconds longer is about 50-100 times how long it took to do the one liner in javascript. Extrapolate that to generally 50-100x development time for the development of an entire project and you're looking at weeks to months longer development time to solve the same problem. Rust is slower to develop in by a significant factor than js, python, ruby etc.
What I was trying to get at with the (silly) example is that the time-to-first-execution of a working program on good input might be much faster with something like JS, but the time to have a debugged version that fails gracefully (and clearly) on operational errors may not be. It’s okay to disagree, and it’s also okay to agree and still feel Rust makes the wrong tradeoffs. I just mention it because I think people sometimes overweight the time-to-first-run.
