Uses QuickJS through the rquickjs crate to evalulate JavaScript source code or QuickJS bytecode.

Refer to the crate level documentation to learn more.

Example usage:

use anyhow::anyhow;
use javy::{Runtime, from_js_error};
let runtime = Runtime::default();
let context = runtime.context();

context.with(|cx| {
    let globals = this.globals();
    globals.set(
        "print_hello",
        Function::new(
            this.clone(),
            MutFn::new(move |_, _| {
                println!("Hello, world!");
            }),
        )?,
    )?;
 });

context.with(|cx| {
    cx.eval_with_options(Default::default(), "print_hello();")
         .map_err(|e| from_js_error(cx.clone(), e))
         .map(|_| ())
});

Publishing to crates.io

To publish this crate to crates.io, run ./publish.sh. You will likely need to run git submodule deinit test262 so the working tree is small enough for the publishing to succeed.
