Tag: Maintainability

Good food for thought here from Nolan Lawson about rewriting JS tools in “faster” languages.

The point that a rewrite is often faster simply because it’s a rewrite is a very valid one—over time we add more features/functionality to our code and it starts to have a cost not just on perf, but on maintainability as well. A rewrite lets us start with those learnings already in mind.

But my favorite point is around the accessibility of JavaScript tools built in JavaScript:

For years, we’ve had both library authors and library consumers in the JavaScript ecosystem largely using JavaScript. I think we take for granted what this enables.

I wrote about this a few years back, but having JavaScript available on the front-end, back-end, on the edge, and in build tools is a powerful way to let developers extend their reach into different part of the tech stack and any decision to move away from that needs to be VERY carefully considered.
