Why I’m skeptical of rewriting JavaScript tools in “faster” languages | Read the Tea Leaves

I’ve written a lot of JavaScript. I like JavaScript. And more importantly, I’ve built up a set of skills in understanding, optimizing, and debugging JavaScript that I’m reluctant to give up on. So maybe it’s natural that I get a worried pit in my stomach over the current mania to rewrite every Node.js tool in a “faster” language like Rust, Zig, Go, etc. Don’t get me wrong – these languages are cool! (I’ve got a copy of the Rust book on my desk right now, and I even contributed a bit to Servo for fun.) But ultimately, I’ve invested a ton of my career in learning the ins and outs of JavaScript, and it’s by far the language I’m most comfortable with.
