Top 4 JavaScript javascript-engine Projects

ChakraCore

15 9,028 5.3 JavaScript

ChakraCore is an open source Javascript engine with a C API.

Project mention: This year in Servo: over 1000 pull requests and beyond | news.ycombinator.com | 2023-12-18

I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:
https://github.com/chakra-core/ChakraCore
Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

jsvu

6 1,833 5.9 JavaScript

JavaScript (engine) Version Updater

Project mention: Be aware of Arrays - V8 engine advice | dev.to | 2024-02-13

For debugging elements kinds to figure out a given object’s “elements kind”, get a debug build of v8 (either by building from source in debug mode or by grabbing a precompiled binary using jsvu), and run: out/x64.debug/d8 --allow-natives-syntax Note that “COW” stands for copy-on-write, which is yet another internal optimization. :))
