[duped]

Be warned that V8 is a behemoth and adds 100+MB to your binary size, is quite slow to link, and is not practical to compile from source for most projects. If you want a lighter weight JS runtime there's quickjs, if you want WASM there's wasmtime.

Personally I don't think it's a good choice for what it seems Roto is used for (mission critical code that never crashes) since TS doesn't have a sound typesystem and it's still very easy to fuck up without additional tooling around it.

There's also Duktape for just JS minus the WASM (at least I don't think they've implemented WASM yet).

I think QuickJS wins over Duktape for ES5 compliance, though it's been a few years since I was evaluating embedded JS. They're both extremely easy to integrate into an application, in contrast to V8

Fair, I'm not quite as familiar, but always like to bring up alternatives in case they're helpful. My favorite HN comments lead me to new alternatives for programming.
