1 Year of Research coming to an end. 8 Months seeing no results, Almost quitting twice. November/December of last year finally seeing a very narrow path to a universal 2x perf improvement on every modern JS parser which would take me another 4 months to build. This will land in oxc_parser fairly soon speeding up OXLint, OXFmt, Vite, Rolldown, Deno (oxc consumer) almost immediately. In the long term it's likely that it will land in V8/SpiderMonkey/Bun/JavascriptCore/Typescript/+ Every other JS parser implementation The wins come from a few key elements, obviously 1 novel "SIMD For Context Sensitive Languages" the other key elements take it from a 20% win e2e to a 80-200% win (99% of files will see a 80-100% perf improvement). These key elements translate to any AST design and thus will speed up not only all JS tooling but every major browser when complete.
