#QuickJS-NG 0.16.0 released, and it's a big one! Regex perf improvements, all stage 3 iterator proposals, and many more! Check it 👉 https://github.com/quickjs-ng/quickjs/releases/tag/v0.16.0

QuickJS-NG is “a fork of the original #QuickJS project by Fabrice Bellard and Charlie Gordon, after it went dormant, with the intent of reigniting its development.” That's great: I wouldn't want to be caught with an unsupported runtime.

I'm very glad I looked through the project's issue list, though.

https://github.com/quickjs-ng/quickjs/issues/1172 describes that in a benchmark, -NG is 10% slower than the original. Unfortunate, but it's understandable that -NG could have become bloated over time with all the extra coding.

The truth surprised me: the original is still being updated and has performance optimisations that -NG haven't incorporated yet! So not quite dormant, then!

😂 Look, someone created a #dynamic #language called "Zef" (because why not?) and now believes they can compete with #Lua, #QuickJS, and #CPython. 🚀 Just another wild ride through "how to optimize your #hobby #project to do something totally unnecessary" land! 🛠️

"Security researcher Sean Heelan recently tested two sophisticated systems built on GPT-5.2 and Opus 4.5, challenging them to develop exploits for a #zeroday flaw in the #QuickJS Javascript interpreter.

The results point to a significant shift in offensive cybersecurity capabilities, where automated systems can generate functional attack code without human intervention."

#CouchDB 3.4.2 is out! 🎉

We held a Meetup recently to take a look at the big 3.4.0 feature release that includes #QuickJS and #Nouveau (full recordings: https://vi.to/hubs/couchdb-berlin).

While the Neighbourhoodies worked with Nouveau to prepare presentations, we came across 6 bugs that get fixes in this release — shoutout to Alex Feyerke for finding them! Haven’t upgraded? You’re running out of reasons not to 😉 As always, if your team need help, reach out.

@mre Another project that embeds JS inside #WebAssembly through #QuickJS is https://github.com/justjake/quickjs-emscripten by @jitl. I find Jake's solution particulary interesting for its "asyncify" feature, allowing you to expose asynchronous functions into QuickJS that the embedded JS code can access as if they were synchronous. The feature is based on Emscripten's ASYNCIFY and suspends the WASM execution while awaiting a promise.

We have updated and switched to use quickjs-ng in radare2, which is a fork of quickjs, but quite more updated and active. The main reason is for maintainance and portability reasons, so we can just upstream our patches 🔥 Kudos to @satk0 for the integration work! #quickjs #javascript #radare2
