The testing for Svelte, Solid and React all contained significant implementation errors, resulting in way lower scores. They were largely written by LLMs. PRs have been filed to fix all of these issues.

Svelte version:

- cloned arrays thousands of times

- Used Svelte v3 (V5 comes out soon lol)

Solid version:

- Had unnecessary style bindings that other solutions did not include

- Can be done without hydration, making it more comparable to Fastify example

React version:

- Run in dev mode LMAO
