  • Boa JavaScript Engine v0.17 released

    For example, we have implemented Hidden Classes (what we call Shapes) and constant folding. We are also looking into NaN boxing, Inline Caching, and a control flow graph construction, to implement optimisations such as dead-code elimination.

    Yeah, pretty much. I'm not sure if we're gonna need to implement Static Shapes first but at least we need to make it possible to separate codeblocks from contexts for this to be feasible.

    Hi, I'm looking for full time work and I'm interested in roles related to compilers, developer tools and systems. I'm a college senior(graduating on May, 2023) and have been working as an [IOS Developer]( for the past two years. At University, I took a compilers class where I learnt to use LLVM and MLIR to compile programs to various architectures. In Oct. 2022, I was selected to attend the [Programming Language Implementation Summer School]( where I got to learn about compiler implementation and language tools from leading researchers around the world. Recently, I have been contributing to [Boa](, an embeddable Javascript engine written in Rust, by fixing issues and implementing features to improve conformance with ECMAScript specification. Aside from working on compilers, I have volunteered at conferences like ICFP'21 and PLDI'22 to familiarize myself with latest research in the field of compilers. You can find more information about me and my work in my [blog]( and Github [profile]( Thank you for your time and consideration.

    I have great news
  • Dune: A new JavaScript and TypeScript runtime built in Rust
    5 projects | /r/rust | 7 Sep 2022
    I would be curious how much effort it would be to swap boa for V8 to have an all Rust runtime :) If it's not meant to be a production-ready project anyways.
  • Implementing a safe garbage collector in Rust
    4 projects | | 29 Apr 2022
    Although you probably could use it for something else, Boa[1] is a good demonstration of this (it uses the GC crate, but the same principle probably applies).


  • A python interpreter written in Rust?
    6 projects | /r/rust | 27 Mar 2022
    Deno uses the V8 JavaScript engine, which is written in C/C++. There is a Rust JavaScript engine called Boa though.
  • Boa release v0.14: A JavaScript engine written in Rust
    3 projects | /r/rust | 16 Mar 2022
    One of the big changes in this release was to port the whole execution of JavaScript to 2 steps, a compiler and a VM. You can find more information about the VM here:

    Author here. A few other Rust projects to note that I didn't mention in the original post I've since found:

    - Boa (JS engine in Rust) –

    - RSLint (JS/TS linter in Rust) –

    - Node version manager in Rust –

    If you know of any other popular ones, let me know. I'm keeping a list :)

  • Boa release v0.13
    3 projects | /r/rust | 30 Sep 2021
    We did! We have an issue related to that, but right now we are focusing on having a 100% compliant engine :)
