JavaScript’s grown-up sibling just entered the chat.
Strongly typed, zero config, and built for people who want their code to just work.
Josh Vlk joined Jared to explain why ReScript isn’t just another TypeScript flavor—it’s a full rethink of how we build for the web.

ReScript is the future!
In JavaScript, there are a hundred ways to solve the same problem.
In ReScript, there’s one—and it actually makes your life easier.
Josh Vlk explains why enforced consistency might just be the future of clean code.

It's so close! No more JS.Array2 or Core.Array, it's just Array! ReScript is growing in capabilities while also becoming more simple and easier to learn.

I'm using tsgo + oxlint + oxfmt for the first time.
It's all *so fast*. Small project (~1k loc, ~10 files), but type checking in 90ms, building in 60ms, linting in 70ms, and formatting in 80ms is fantastic.
🚀 The future of web dev tooling is bright. Nice work @typescriptlang.org and @voidzero.dev!

Let's go! If TypeScript is getting faster after a compiler rewrite, ReScript can do it too! It's gotta always be the fastest option out there for typed web development.
So this crab jumped into our build system and things got out of hand.
End result: a brand new, super fast ReScript build system.

Been building a @rescript-lang.org MCP server lately, letting an LLM truly see a codebase.
If you haven’t met ReScript before, this one’s still worth watching . It has a clear case of how localized MCP servers can lift developer tooling.

I do highly recommend Rust (though I came from a Python background, likely have different use cases)
For a 'Typescript but stricter' may I interest you in ReScript? rescript-lang.org
@fham.dev will have a lot to say
Gleam is also cool: runs on BEAM, compiles to JS!

I've finally managed to get the @rescript-lang.org site building with @reactrouter.com! I have some bugs and styling issues to sort out, but I've deleted so many dependencies that we needed for the Next.js page router.
And we get to use more of the new @rescript/webapi library!

I wrote my first non-trivial service with @effect-ts.bsky.social this week! I wanted to fire off a tracking call in a web worker, and using Effect I was able to always capture errors, perform retries, and spin out fibers for each tracking call. It's fast and never throws an error.
