i’ve argued for writing tools in technology fit for purpose. a lot of web development tools being written in javascript (and then typescript) was because web developers had to build their own tools, and typically these folks were extremely comfortable with ruby and/or javascript, so naturally they reached for them. some of these important tools can have massive speedup gains just by switching internal data structures and algorithms. in my opinion, every rewrite implicitly makes this switch but the importance of these decisions are subsumed by the detail of the implementation language. prettier can be faster with a better algorithm. then maybe rust can help it take advantage of specific operating system improvements not naturally available to node. regardless, bravo and onwards with more rewrites!
