We have a PR to enable Intl in Hermes. It is some binary increase, but not a lot, about 3% (precise numbers in the PR). github.com/facebook/herme… Should we just enable it, or should we maintain two separate builds with all the associate complexity.

As of yesterday, Hermes supports logical assignment operators: ||=, &&= and ??=. It ended up a fairly small change - the tests are larger than the actual code. github.com/facebook/herme… #javascript

A major milestone: Hermes can now parse the entirety of Facebook's JavaScript codebase, both for web and RN, including all ES6+ features, JSX and Flow type annotations, no Babel or any preprocessing. A single server VM with 24 workers parses 450MB/s. (1 of 3)

We have recently added ES6 Proxy support to Hermes. Help us test it in your React Native 0.62 based app with npm install hermes-engine@v0.4.2-rc1 and let us know!

Cross-compilation of Hermes to Wasm/Asm.js has finally landed on Github (for many months it was just a local experiment on my laptop)! Now anyone can compile and run Hermes in Node.js or in a browser... A NPM with a packaged Wasm/Asm.js build will follow soon.

We just landed another 5% memory win in Hermes github.com/facebook/herme… . It is a design change that was planned a little more than a year ago. More are coming.

The Hermes JS Engine team has been working hard to improve memory usage. Since July we have decreased our RAM footprint by more than 30% and there are yet more significant savings to come! #hermesengine #javascript #ReactNative

That was all about personal time and lack of sleep.😴 Right now RN is getting better and better and I could really take a rest 😊 Thanks to Facebook and RN community.

Thanks to the release of @HermesEngine, I could have a work life balance right now. It's a good time to talk about the journey to contribute RN this half year. [Thread N]
