I don't think calling it a machine is implying that we understand how it works internally (to a much greater extent than we actually do). Or even that we fully understand how it tends to behave in practice, out there in the "real

Reminds me a bit of jsonnet ( https://jsonnet.org/ ) which didn't catch on much as far as I can tell. I see very little practical value in a DSL like this. Using an existing language with an extensive ecosystem and great

Kind of. From a brief look, it looks very framework-y and all-or-nothing (though I could be wrong, they do have a page about gradual adoption at least https://www.pulumi.com/docs/guides/adopting/ ). I was pict

I feel like trying to use a "dumb" declarative config language for everything is part of the problem. The domain is not simple enough for that, so you end up with all kinds of weird scripts around it all, or other templating/

I remember one keynote where he was talking about slowing PC sales and a huge rise in iPad sales (tablets were relatively new back then). Yet he didn't credit the two most obvious reasons - market saturation (everyone already has a PC)

I very much doubt that is a major reason. Language itself is rarely the issue, unless you're reusing code from other parts of the project (which many projects are, e.g. VS Code with Monaco). I have spent far too much time on HN recentl

I wonder whether GraalVM native image will play a bigger role in desktop apps in the future. Kotlin + TornadoFX + native-image (if it is supported) sounds like a pretty comfortable to use UI stack.

I think eslint would flag it as well for what it's worth ( https://eslint.org/demo , you have to set it to newer ES version in the Rules configuration at the bottom of the page).

Whether it is actually good is subjective though. There are tons of existing cross-platform UI frameworks (Qt, wx, libui, JavaFX, TornadoFX, ...). The comment above says "Everybody would jump to Swift [for new projects] if it meant a

This is especially true with `| undefined` helping address the billion dollar mistake.

Can you show an example of such a bug? The only thing I can think of is return value which will get flagged by TS as unreachable code (you can try it in https://www.typescriptlang.org/play )

Does it only redraw things on change, or fixed at 60 FPS no matter what? Does it redraw the whole screen, or only the parts that have changed? A lot of the screens show FPS info, so it's not immediately obvious.

Is the type system at least as rich (or richer) than TypeScript's? Can I do stuff like `Partial<T>`, `Omit<T, K>` intersection types, etc? Is structural typing the "default"?

Yeah, I'll edit the original comment to clarify that I mean hashes of dependencies.

How? Say I have `script.ts`. That file exists locally on my computer and the code inside it is trusted (say it was downloaded from a trusted github project via https). It contains import { dependency } from 'http://what

Can checksums/hashes be specified directly in the source file? EDIT: I mean hashes of dependencies. That is important for single-file scripts, if this is meant to be useful as a bash replacement for scripting. Having to download two se

To sort of answer my own question, there is one more "leak" I forgot about - array bounds are unchecked https://github.com/Microsoft/TypeScript/issues/11122 , which can give you `undefined` (though n

I know how it works. I'm talking about practical implications . In practice, say I have type User = { name: string, email: string } let loggedInUser: User = { name: 'Bob', email: 'bob@examaple.com' }

Yes, it is theoretically possible for a TypeScript type to be "wrong" and the underlying variable to have a different type. But there are only a few ways in which that can happen: - a bug in type definitions - a JS library with .d

by realharo 6y ago
Regarding the `if`, it only makes sense to test for things that the type actually contains. So if I have a type `User|undefined`, testing `if (user === undefined || user === null)` is pointless, as `null` is not part of that type. It would

by realharo 6y ago
I have never encountered issues with JS libraries lying in their type definitions (like not including `T|undefined` in the type if `undefined` is a possible return value). More often this can happen with external data (typing incoming JSON

I'm not saying it can't be done, I'm saying it would take a lot more effort (by a huge amount, plus more in prototyping phase of development when you're trying stuff out), and in the process you will likely lose many o
