Fabrice Bellard 的 QuickJS

Fabrice Bellard 跑去寫了一套 JavaScript engine 出來:「QuickJS」。

以 ES2019 當底實做的 JS engine:

Almost complete ES2019 support including modules, asynchronous generators and full Annex B support (legacy web compatibility).


Passes 100% of the ECMAScript Test Suite.

在大小的部份,比起其他的 engine (與 package) 來說的確是小很多,不過 190KB 這個大小對於 embedded system 來說還是有點微妙 (但對於想要包 JS engine 進去用的人應該是頗開心的):

Small and easily embeddable: just a few C files, no external dependency, 190 KiB of x86 code for a simple hello world program.

不愧是 Fabrice Bellard,搞出了 LZEXEFFmpegQEMU 後跑來搞 JS...
