ECMAScript excitement 😉 Congrats to @ashley-c.bsky.social on advancing the Composites proposal to Stage 1 at TC39 today 🎉 This is the evolution of Stage 2 Record & Tuple which has now been withdrawn. A key difference is that Composites are objects, not primitives. github.com/tc39/proposa...

I wrote an article about the Emergent #Testing paradigm that I'm using to test #FunctionalScript, #TypeScript, and #JavaScript code, but it can be applied to other programming languages as well. I would like to hear your feedback. medium.com/@sergeyshand...

Thanks, GitHub, for free CI for OSS projects. However, it's very hard to protect branches, if your project has a lot of small GitHub CI jobs. From now on, the FunctionalScript has only 6 jobs (3 OSes x 2 Architecture) instead of 33. github.com/functionalsc...

Let me know if you plan to attend CascadiaJS 2025 and would like to meet.
Until we build decentralized, trusted networks for software development, the FunctionalScript project won't depend on other packages (NPM or crates).
One of the coolest features of content-addressable programming languages is that copy-paste is not an anti-pattern. The PL build system will deduplicate them anyway.
Hi Seattle friends! 👋 Don't miss the @seattlejs.com meetup tonight! - Talks from Evan Boyle, @sergey-shandar.bsky.social and more - Covering React, FunctionalScript, Robotics - Fun hangs with fellow devs PLUS get a promo code to get $50 off your CascadiaJS ticket 🎟️ Link to RSVP below ⬇️
Over the last few days, I have worked on eDSL to define grammar in #FunctionalScript using #BNF. It's done. Also, I added a function that can create a LL(1) parser from the eDSL. It should be easy to add others, like LR(k). jsr.io/@functionals...

Sergey Shandar@sergey-shandar.bsky.social · 2y agoUnpopular opinion: if a null pointer in high-level programming languages is a billion dollar mistake, then direct access to I/O (input-output) should be a trillion dollar mistake.
FunctionalScript library received several new features today, such as: - #SHA2 64-based (SHA512, etc) - msbUtf8() function, to convert #JavaScript #UTF16 strings to #UTF8 bit vector (as #bigint). github.com/functionalsc...

It would be very cool if #TypeScript has a possibility to add compile time tags to types. Two types with different tags are different at compile time but the same at run-time. Something like gist.github.com/sergey-shand...

Unpopular opinion: code tests should never ever depend on a specific #test #framework.
