100% this. People forget when using dynamic languages they are trading up front cost - its easier to write the code but harder to test. In trivial or exploratory coding the tradeoff can be good, but it is a tradeoff.
That being said, using rust can be really nice for exploratory coding. If don't worry about edge case (use unwarp()/panic!) and don't worry about memory efficiency (use clone()) it still produces fast, memory efficient code.
