I don’t know I really hate when jumping to definitions in libraries, I often just land in the “typings” file. I also think that the type-system is often incoherent, has some weird side-effects and often leads to overengineering your typings… I just generally avoid Javascript based languages (which unfortunately is not really possible in frontend…)
Typescript has many shortcomings. About every language does. But it’s an undeniable very strong benefit that you can code the front and backend with it easily. It runs everywhere. It’s reasonably fast, for aws lambdas I found it had really good cold start time. I suspect because node is built on V8 which is highly optimized to get code running asap.
That accessibility and versatility makes it in my opinion the best general purpose language right now.
In backend I’m absolutely happy I can avoid it, there are more solid and more performant languages. I just can’t program in the style I want without loosing massive performance in java/typescript, like in a functional composable style, it results in a mass of allocations, I hate it (because it looks cleaner and is a better architecture IMHO). Rust does a much better job here… I’m also not a huge fan of the type-system, it’s super flexible, but has some incoherence, you tend to overengineer your types, no real ergonomic algebraic data types etc. It also has so many weird design decisions (e.g. prototypal inheritance) I don’t understand and don’t like…
I think Rust comes probably from the other direction, I can soon write my frontend in Rust without having much ergonomic loss (lets be honest, UI frameworks are currently more “solid(js)” in typescript than Rust, but I think that may change in the future…)
Probably should clarify. I think there are better languages in design and safety for backend.
However when it comes to a language you can pick up and crank out code for JS/TS is hard to beat. There’s libraries for everything and if your a full stack dev your probably really familiar with all the ends and outs.
If I have time and I want to make a solidly engineered product Rust is a better option. But often I’m pressed for time and TS can make a solid enough and performant enough product.
