Fabrice Bellard, the creator of FFmpeg, a command line tool to convert audio and video formats and QEMU, open-source virtual machine monitor, along with Charlie Gordon, a C expert, have together announced the first public release of QuickJS.
The project is co-created by Fabrice Bellard and Charlie Gordon. Bellard has made a number of contributions including the Tiny C Compiler, FFmpeg, and QEMU. Even the formula used to calculate the nth digit of π in base 16 was created by him. Programming legend, Bellard also holds the World Record for calculating pi to about 2700 billion decimal digits in 2009. Here’s what QuickJS offers:
ES2019 Support: This is the first JS engine to offer ES2019 specification. The JS specification brings almost complete engine features including modules, asynchronous generators, and full Annex B support. This currently does not support realms or tail calls.
Small structure: The small and easily embeddable structure of QuickJS does not have any external dependency. The engine is formed by only a few C files.
Faster interpreter: The interpreter of QuickJS shows impressive speed by running 56,000 tests from ECMAScript Test Suite1. The engine takes just 100 seconds to complete the tests on a single-core CPU.
