That's ironic, because as a fullstack developer, I don't want to touch Go exactly because of it's lacking type system and how it manages dependencies. Typescript has the best type system among modern mainstream languages, and although you're right that Node is not well suited for CPU intensive applications, the most part of backend work is IO bound, where async/await works perfectly — waiting for reply from the bd looks and works much more natural than with Go's primitives.

Typescript type system is both powerful and lacking, and with a syntax that is horrendous to do anything complex. It gets even worse than regex in the "write-only" direction. And you can do black magic but at the same time very basic things are still not possible. I would argue that the Python type system is actually better because you can build on it with regular Python instead of typescript weirdness and because you can use it at runtime. The fact that typescript does not support any kind of reflection makes it very limited for a script language. Rust type system on the other hand is also limited in refection but it is not a scripting language so it's more acceptable, and at least it integrates very nicely with features such as pattern matching and control float which you don't have in TS. TS also has a way too complex option list which is becoming nearly as annoying as ESLint to configure, with basic safety disabled by default and rules that are just annoying and add no safety whatsoever in the "strictest" config.

  Can you please provide examples of what do you consider "write-only" types? Because so far what you've described is the exact opposite of my experience as a Typescript developer. As far as reflection goes, I see how it could be useful with other languages with less powerful type systems, for example, to build a deserialiser. But with Typescript's type inference I just never felt the need to reach for a crutch when I can use a proper solution.

> Typescript has the best type system among modern mainstream languages, I wouldn't call something the best when it's disabled by default, even after considering the fact that it's neither part of the language nor the platform, and needs multiple dependencies in order to run, at which point it has worse type-checking than every other language.

TS's type system is nice but to call it "the best type system among modern mainstream languages" is a bit of an overstatement.

  I would say TypeScript is second only to Rust

    Check out Scala's type system. I don't think you'll miss anything that TS can offer there.
