I’ll throw my 2¢ in on TypeScript → JavaScript. The typings accelerate development significantly (if the developer doesn’t fight them and make everything
any), and you can write to modem JS when you have older runtimes.But more you can do full stack from cloud infra (Infrastructure-As-Code with something like AWS-CDK or CDKtf) to deploy and orchestrate front-end to back-end.
Yeah but the ecosystem drags it about as far down as you can go.
Backend development for large applications relies on stability, the JS ecosystem has anything except stability.This is okay for FE development where you naturally have a lot of churn.
It's a reasonable expectation that a backend built today should be maintenance free and stable over the next 5-10 years if no more features or bugfixes are required. And is buildable, as is, anywhere in that timeframe with minimal or zero additional work.
Additionally, strong backends in the same ecosystem are similar, they use similar technologies, similar configs, similar patterns, and similar conventions. This is not the case for JS/TS backends, there is incredible churn that hurts their long term stability and the low-maintenance requirements of strong enterprise, and even more importantly small businesses backends.
Mature ecosystems provide this by default this is why C#/Java is so popular for these long-standing, massive, enterprise systems. Because they are stable, they have well established conventions, and are consistent across codebases and enterprises.
This is a perspective most devs in the ecosystem lack, given that half of all developers have < 5 years of experience and the vast majority of that is weighted into the JS ecosystem. It takes working with systems written in python, TS, JS, C#, Java....etc to gain the critical insight necessary to evaluate what is actually important in backend development.
Edit: to be clear this isn't just shitting on JavaScript because that's what people do, I work with it everyday, TS is by far my favorite language. 2/3 of my career is with JS/TS. This is recognizing actual problems that are not singularly solvable with the ecosystem that pulls down its liability for backend development. There are languages and ecosystems are much better for your back end it's not that scary to learn a new language (many of my co-workers would disagree it's not scary 😒)
I’m not sure what you mean by unstable ecosystem. I can presume you mean it’s easy to gain tech debt since there’s such velocity in the node/JS/TS ecosystem (and I agree not all of it is good).
I haven’t found it to be an issue. My job is a contract system engineer guiding companies in fixing tech debt, so I am very attuned to it.
Specifically I’d say the tooling in the last year or two has gotten much better at stabilizing an environment for node/deno development in particular. Tools like fnm, projen, and esbuild mixed with installing tools per-project (using
npxto run them) instead of globally for development allows flow project to project on the same machine without having conflicts of tooling versions. Combine that with Docker for deployment and something built today should last 4-5 years with little maintenance and not having to make any changes except for security patches.Not that there’s not hiccups. The whole CJS/ESM nightmare is still going (but near an end I feel).
I also feel like 4-5 years without maintenance is not something you really want. In the rare case you do, then I’d say JS is likely not for you. I’m not sure what language is. C or C++ most likely. Those have been around forever, and will never go away. Modern C++ has a lot of great features to handle memory management automatically, functional programming capabilities, compile-time metaprogramming, and OS abstraction, so that’s what I’d recommend for something that needs to last forever with minimal changes. (Thinking like a COBOL replacement.) After all, that’s what node and the JavaScript engines are written in.
My biggest issue with Java in particular is the predatory enterprise ecosystem. I spend a lot of time helping companies get away from that for cost reduction and lock-in issues.
One more point for node: it’s hands-down the most optimized interpreted engine in the world. This can be determined simply by the size of the companies that work on it and that absolutely depend on it being it’s best for their bottom line. Google, Apple, Facebook, and Microsoft among them. Billions spent on that optimization. Just sayin.
