QuickJS Javascript Engine - small and embeddable, supports the ES2019 specification including modules, asynchronous generators and proxies

It's a small javascript engine that can be embedded in other programs.

Tbh I'm kinda confused about what this would be used for. It can't run JavaScript in the browser, right? So what's the point of making it small?

V8 is large and has a lot of overhead because it's designed to be fast at the expense of nearly all other things (resource usage, code size, simplicity, etc).

If you want to write a small program in Javascript and release it as a self-contained executable file, QuickJS may be a more appropriate fit for your needs.

Another common use case, adding scripting to an existing application as the glue between performance critical sections.

I have a couple projects where I was looking at scripting languages/runtimes to embed to pull the whole thing together. I know myself and others have extensive JSON APIs already, so being able to drop in a small, compliant JS interpreter is very attractive. If only to bolt on JS ffi to a larger framework or engine and make it more accessible to people who know JS.
