已经用上 Rust 重写的 TypeScript 编译器了，拿前端老项目一试，比微软官方编译器快了一倍！🚀 它叫 tsc-rs，是博主 Theo 刚开源的。他晒了笔按 API 价算的账：先让 Codex 写了几个月，烧掉 40 多万美元，兼容性还卡在 84%。换成 Opus 5.5 推倒重来，两周花 2.4 万美元就做成了，全程他一行代码都没读！ tsc-rs 的参数和 tsc…

🔥 GitHub Hot Picks (Oct 8, AM) 1. ts-rust — the TypeScript 7 compiler ported to Rust by AI agents, type-checks ~2x faster than the Go version 2. RAD Debugger — Epic Games' fast native debugger, now…

A later audit of that run found 70 failing tests and a build 2.6 to 3.4x slower than Go. The README is upfront about speed too: about 1.6x faster than tsc 7 on six real apps, and bun check is faster…

theo's agents ported TypeScript 7, Microsoft's native compiler, to Rust. He says $400K of Codex tokens got nowhere on the same job, and $20K of Opus finished it in two weeks. He hasn't read a single…

JUST IN: @theo open-sourced ts-rust (aka tsc-rs) > ts-rust ports TypeScript’s compiler and language server to Rust, delivering faster type checking, WASM support, and built-in Effect diagnostics.

Theo今天发布Rust版TypeScript编译器tsc-rs，仍是早期版本。 我会用“故意写错”的代码比较：同样的类型错误，报在哪一行？改完文件后，旧错误会不会留下，新错误能不能找到？ 重写工具，除了比速度，也要看它怎样发现错误。少报错不一定代表代码更正确。 #AI #TypeScript

Announcing tsc-rs (aka ts-rust), my complete rewrite of the Typescript compiler, type checker, and LSP, all in Rust. This is a project I've had agents working on for 5 months now. I burned ~$400k of…
