On the author’s point of a ā€œdebug buildā€ with runtime type checking, there is ts-runtime-checks [0], which looks to do something similar! I don’t have any experience with it however, just seen it looking at typescript-runtime-type-benchmarks [1]. There’s a few other similar things there too [0] https://github.com/GoogleFeud/ts-runtime-checks [1] https://github.com/moltar/typescript-runtime-type-benchmarks
In What can TypeScript learn from Zig? What can Zig learn from TypeScript?
This is a blog post I've been putting off writing for a while; I'll try to tl;dr it best I can given it's somewhat off-topic: * TypeScript's lack of runtime types and stable reflection APIs make it hard to have any guarantees of type soundness without either code generation (e.g. schemats) or complex type programming to convert a runtime representation of a type to a static type (e.g. io-ts). I find this very frustrating when doing web backend programming, where you are constantly doing i/o with external services (whether HTTP APIs, or input from client requests, or database interaction). This is particularly maddening because there's no de facto standards (seriously, there are a lot of these libraries: https://github.com/moltar/typescript-runtime-type-benchmarks), so it's not easy to e.g. find a DB library that will let you define an io-

ts schema that a query should match without re-wrapping things yourself. Basically: if TypeScript had runtime types, and an `as` cast threw an exception when a value doesn't match the specified type, I'd be much more inclined to keep using it. I genuinely think that's table stakes for a type safe language. (and lest you think this has to be how TS works given the nature of how it's compiled to vanilla JS, I suggest you take a peek at Sorbet, which knew this was necessary: https://sorbet.org/docs/runtime) * The TS ecosystem is generally underwhelming. I don't think any HTTP framework for it is particularly good, nor any ORM/query builder. I think there are a lot of really neat experiments still happening in this space, and it seems like every day GitHub's little "explore repositories" sidebar shows me another cool library someone's built for TS trying to solve some of these problems, but it's all early stage stuff with a bus factor of 1 and a long todo list. To be fair, _Kotlin's_ ecosystem actually has a lot of these problems; the semi-official Jetbrains-maintained Kotlin web framework and DB access library both have a ton of untriaged issues and seemingly little production use. The good news is, at least on the server, you can completely ignore the "Kotlin" ecosystem in favor of the Java ecosystem, and this is _shockingly_ effective. Just about every JVM framework I've seen has some kind of officially-maintained Kotlin adapter, presumedly because it's not hard to sell Java developers on "what if you could keep using the exact same tools with a nicer language." These adapters aren't even needed, mind you, they just provide nicer APIs that can use Kotlin language features. Javalin + JDBI is infinitely nicer out of the box than trying to turn Express and Knex into a production-ready API with anything approaching type safety. * This isn't a make-or-break thing, but Kotlin is just generally _nicer_ than JS or TS in a lot of ways, while still having a very similar programming style. For example, the collection types are far more robust than something like Lodash (let alone the absolute joke that is the ES6 Map/Set API).
