This is a very good talk but I wonder if this alternate compiler design has actually made the TypeScript compiler slower in normal compilation mode. If you really do "helicopter in" to every point in the syntax tree and run IDE qu

This approach uses much less memory, gives a render that is exact instead of approximate (it doesn't suffer from corner clipping or grid resolution issues as you zoom in), and is quicker to do an initial render because there's no

Right now the only implicit conversions are null to nullable types and smaller integers to larger ones. There is no "===" right now and "==" requires equal types. I may consider aligning this more with JavaScript in the

There is no "any" type since ThinScript is an ahead-of-time compiled language and emulating dynamic types is a non-goal. Types are required and omitting them is a syntax error. Right now "let" is an alias for "var&q

Yes. As the parent comment said, you could try to to choose a subset of TypeScript that's relatively efficient to help avoid some of the issues with JavaScript. The problem is that the TypeScript language itself lacks certain primitive

I don't consider the design of TypeScript a weakness at all. TypeScript is really well designed and is great at what it does. The type system they came up with is pretty optimal for modeling real-world JavaScript code. But the tuning t

I'm not planning on supporting return type inference since I actually don't like that feature of TypeScript, but I could be convinced otherwise. It really harmed API readability for me when I tried to use it. All declarations in T

I considered that but I'm worried that won't work with WebAssembly because it's a more memory-constrained environment. Your app may generate a ton of data in a frame and run off the end of the address space. I guess I'm

I'm planning on experimenting with either pure reference counting (Swift), reference counting + cycle collection (Python), or garbage collection. I'd love to hear about what people are doing for emscripten actually. I've read

I plan to do it eventually. I've implemented generics before so that's not the issue. It's just hard to get the design of generics right when the compiler has multiple targets. You want to emit compact JavaScript code and at

Yes. TypeScript doesn't have a sound type system and it comes with a lot of baggage: * Using hashtables in TypeScript relies on the representation of JavaScript objects with strings as properties. Emulating JavaScript's in-memory

Yes! I considered this and it's an interesting idea. ThinScript may end up being pretty opinionated about memory allocation though (I'm not sure yet if I'm doing pure reference counting, pure garbage collection, or some combi

Oh wow I did not expect this to be up here this soon. Warning: two-week-old project. I've got a lot of plans for this but it'll take at least a few months for this to be anywhere near useful. Right now it's just an experiment

> Displaying a JavaScript dialog—alert, confirm, or prompt—no longer activates the calling tab. This seems like a regression to me. If some page is bugging me then I'd like to know which one it is so I can close it.

I currently write compilers that target JavaScript and have looked a TypeScript a lot for something like this. In practice, TypeScript isn't actually strictly typed. There is a ton of TypeScript code out there that does stuff like run-

Meshes are closer but vector networks also attach specific attributes to edges which is not usually the case with meshes. Examples: control handles (for curves), stroke weight, dash pattern.

Figma is not just a UI mocking tool. It's a full general-purpose vector graphics editor. Vector networks work similar to meshes in 3D.

Graphs have a set of vertices and a set of edges, but vector networks also have a set of faces.

This sounds pretty great. This technique would be really powerful if the worker thread could pass a buffer of the rendered results off to the main thread efficiently for use by the main thread. For example, a game has a worker thread to ref
