how to pass multiple parameters and/or arrays/objects to functions?

Good questions.

First, in order to convert native JavaScript objects into interpreter objects, we're going to need access to the interpreter. One way to do this is to move the API function definitions inside the init function, so they have access to the interpreter variable.

	const init = function (interpreter, globalObject) {
		const funcs = {
			sq: (x) => x * x,
			sq2: (args) => {
				console.log(`sq2`, { args: args });
				return args.x * args.x;
			},
			times: (a1, a2) => {
				console.log(`times`, { a1, a2 });
				return a1 * a2;
			}
		};
		const scope = interpreter.nativeToPseudo({});
		interpreter.setProperty(globalObject, 'scope', scope);
		for (const key in funcs) {
			if (typeof funcs[key] === 'function') {
				interpreter.setProperty(
					scope,
					key,
					interpreter.createNativeFunction((args) => funcs[key](args))
				);
			}
		}
		interpreter.setProperty(
			globalObject,
			'setOutput',
			interpreter.createNativeFunction(outputWrapper)
		);
	};

With that done, now we can convert the JS-Interpreter object args into a native JavaScript object:

			sq2: (args) => {
				args = interpreter.pseudoToNative(args);
				console.log(`sq2`, { args: args });
				return args.x * args.x;
			},

And finally, we need to simplify your loop for defining these functions, so that it doesn't force a definition with a single argument:

					interpreter.createNativeFunction(funcs[key])

Hope this helps!

Thanks a lot for the quick response. I will try it out
