For those wondering, Wasm3 describes itself as "the fastest WebAssembly interpreter". Other webassembly runtimes are JIT based, rather than being interpreters. The project's readme (<a href="https://github.com/wasm3/wasm3" rel="nofollow">https://github.com/wasm3/wasm3</a>) talks more about this decision.<p>For more on the difference, and an explanation of what JIT is, check out this section of the book Crafting Interpreters (<a href="https://craftinginterpreters.com/a-map-of-the-territory.html#shortcuts-and-alternate-routes" rel="nofollow">https://craftinginterpreters.com/a-map-of-the-territory.html...</a>)
