Show HN: Elysia JIT "Compiler", why it's one of the fastest JavaScript framework

Wrote a thing about what makes Elysia stand out in a performance benchmark game

Basically, there's a JIT "compiler" embedded into a framework

This approach has been used by ajv and TypeBox before for input validation, making it faster than other competitors

Elysia basically does the same, but scales that into a full backend framework

This gave Elysia an unfair advantage in the performance game, making Elysia the fastest framework on Bun runtime, but also faster than most on Node, Deno, and Cloudflare Worker as well, when using the same underlying HTTP adapter

There is an escape hatch if necessary, but for the past 3 years, there have been no critical reports about the JIT "compiler"

What do you think?
