You can define a metatable on your objects of interest (or the root table meta table if you don't mind breaking the language's conventions and thus libraries) with __index and __newindex members. Then you can throw in those by cal

TypeScript _itself_ has a branded primitive string type it uses internally.[1] Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented wi

I, too, thought http/2+ would encourage unbundled js, but unfortunately in a world where people are used to whole-program minification and dynamic app slicing, I don't think we'll _ever_ move away from bundlers. The build ste

I think this is funny, since esm being "native" on browsers doesn't really matter until you can convince devs they don't actually need to use a bundler. So long as you're using a bundler, the browser's runtime

At first, I was really excited, because I really wanted this pipeline to work well. I've wanted an automatic FPGA workload offloader for awhile. Then I read that their "JIT" FPGA bitstream still took 2 _hours_ to build becaus

Contrary to what seems to be popular opinion here on HN, I think it's fine they'd entertain keeping their code as JS with JSDoc, rather than TS. It's still typesafe, which is what's important from a maintenance and docum

Eh, wanting to dogfood the JS tooling you're writing is a fairly valid reason, imo. Would dogfooding on TS cover many JS usecases? Sure. But inevitably some things are different. I'm somewhat sympathetic.

V8 stopped dropping free perf wins on the JS community every year a while ago, and people are clearly starting to notice and feel like they need to take matters into their own hands. For some, that means an adventurous rewrite of their libr

When you can write a busy beaver machine in the type system, LOC ceases to be a good indicator or how long something should take to typecheck, imo. If you're frustrated with your build, you should use the trace tools on the TS wiki[1

Errr, why do you need any non-js-runtime tool for this? TS's normal `tsc` command line is a single js file - you can pull it straight from GitHub[1] or unpkg[2] and run it directly in node without installing a full package via a packag

The article mentions the importance of comments and documentation inline in code. I tend to agree - well-written code is great and all, but a good comment can bring in context external to the code and make _why_ code is what it is more clea
