• Ask HN: Interest in a Rust-Inspired Language Compiling to JavaScript?
  5 projects | news.ycombinator.com | 24 Dec 2023

  Hello HN,

  I'm considering the development of a new programming language, drawing inspiration from Rust's strengths, with a focus on compiling to JavaScript. Here what I'm considering are some key features:

  Strict Type System

  Algebraic Data Types

  *Unsafe Mode for JS/TS Interaction*: Facilitate direct interaction with existing JavaScript and TypeScript code.

  No Null Usage: Option/Result patterns to avoid null.

  Trait Implementation

  Backend Development Priority: Initially targeting server-side applications.

  Efficient Compiler Design: Including features like dead-code elimination and partial evaluation, similar to the approach of Prepack[0] (by Facebook).

  I believe this approach could bring significant benefits, especially with recent advancements like Uint8Array and worker threads.

  Would this be of interest to the community? Looking forward to your insights and discussion.

• Do any engines or optimizers product TS-specific performance gains?

  You can still do optimisations based purely on Javascript semantics. This is similar to the first example you give with dead function elimination, and many minifiers do some amount of this already, but you can take it to some extremes. One example of this is the (no longer maintained) Prepack project from Facebook. The core idea is to evaluate as much Javascript as possible at compile time, with the expectation that the result will probably be smaller (albeit less human readable) than the initial code.

• [AskJS] Are there JS minifiers that can compress the code by storing and reusing repeating property/method names and strings?

  It's no longer maintained, but I think prepack is roughly what you're looking for.

• Can something like typescript or elm be AOT-compiled efficiently?

• React I Love You, But You're Bringing Me Down
  3 projects | /r/reactjs | 20 Sep 2022

  i've had code where it intentionally relied on the wrong behavior (missing hook dependencies) and when I fixed it it caused an unintentional bug (hook fired too often or sometimes infinite rerendering). Yes it is more of a bug in the code rather than React hooks issue but it is also really hard to fix/rewrite. while i'd love to jump on the hype train projects like https://github.com/facebookarchive/prepack and how concurrent mode is still experimental after five+ years doesn't give me a lot of confidence.

• Memoirs of a lone JavaScript developer PART 2 : Svelte. An awful implementation of an old idea.
  6 projects | /r/u_liaguris | 17 Nov 2021

  Some real examples in JavaScript can be seen on Prepack[2]. Consequently it is natural to wonder whether we can AOT compile components of client side frameworks, to achieve a reduction in the final bundle size, but also to increase application execution speed.

• React 18 is now in beta

  Less or more it’s likely to happen, and could have been expected 2-3 years ago.

  Especially with https://github.com/facebook/prepack. They want to eventually ship pre-compiled components rather than React.createElement() to end user

  I also think this is why facebook had been investing in `prepack` - https://github.com/facebook/prepack
