Microvium Is Small
How about an (actually small but ES6 feature complete) JS engine for general computers? QuickJS showed so much promise (especially given the pedigree) but it's been dead for a year and it never really delivered on the promise of being small (I guess the code is small, but at runtime it takes more memory than engines with full JIT like V8 or Chakra).Hermes looked interesting, but it's clear it will never be an actual JavaScript engine, it's more like a React Native engine that interprets some subset of JavaScript.Duktape struggles with larger bundles and especially with deep call stacks (same as QuickJS) and the C API gives me strong Lua vibes (which may be a positive for some).
