    > But they admitted namespaces, enums

    And decorators. But this was very early on and they won’t ever do it again unless there’s a drastic change on principle and probably a reorg of global proportion. They categorically reject anything with runtime implications now, and to the point of decorators are actively working to align them with the standard as it’s approaching stability.

    > and interfaces into the language (the latter becoming more and more confusing as type aliases got more expressive) […] Is "as", "is", or "satisfies" expression-level?

    No. All of this is completely separate from the runtime and on a standards course to be treated effectively as comments.

    > But the enums!

    I’m one of the minority who actually likes TS enums, but I strongly suspect they’ll be deprecated, alongside namespaces, as soon as there’s general consensus around types as comments. The TypeScript team considers these mistakes and would very much like to be able to drop them. I’d welcome that too even though I quite like enums.

    The fact is TS has considerable backwards compatibility expectations, and aligning their mistakes with their goals is great on principle but something which would require thousands upon thousands of hours of labor for people to accommodate.

    You can snipe all you want, but if you think it’s that easy to resolve maybe I can direct you to https://github.com/microsoft/TypeScript/pulls

    I’m not affiliated with the team in any way but I’m almost totally certain they’d welcome a contribution that gets them closer to their stated principles where historical designs are entrenched, without breaking workflows for thousands of people and interrupting releases for millions.

    TypeScript has lots of great features and a few bizarrely bad ones. It’s great in spite of itself.

    The main misfeature is their dogmatic refusal to rewrite import paths (citing the “Preserve runtime behavior of all JavaScript code” principle mentioned in this article). Here’s a good summary of the problems this causes: https://github.com/microsoft/TypeScript/issues/42151

    I’m curious, how many people are using TSC only for type-checking, and a different system (eg esbuild or ts-node) to actually compile/bundle/execute their code?

    I think TypeScript would be even stronger if they focused fully on type-checking, and relaxed some of those dogmatic restrictions (and the many, many confusing config options) imposed by the JS code generator.

    Because it's implicit, CJS creates a bunch of resolution issues with Typescript, to the point where if you want to code for the browser, you can't easily can't and have to either recompile with something like webpack to rewrite the module resolution, or add .js to all your TS imports, which already looks weird (you'd think you're importing the .ts files). sip.js has that issue.

    You can't actually narrow `unknown` down to a structure yet, as you have no way to test whether `property in unknown` or not.

    Writing client APIs, that gives you autocompletion is time consuming. You allways endup writing the same kind of boilerplate code or have to use openapi code generators that are a pain to maintain. Zodios was created to make creating frontend (and optionally backend) API client a breeze. It's is an open source REST API toolbox with end-to-end typesafety. It allows you to create a REST API with a clean, intuitive and declarative syntax. It's best used with TypeScript, but it's also usable with pure JavaScript.
