a tiny little lisp interpreter written in js...

lisp.js

var lisp = function(c, context){
	return c instanceof Array ? 
		(typeof(c[0]) == typeof('str') 
				&& c[0] in (context || ns) ? 
			(context || ns)[c[0]].call((context || ns), 
				...c.slice(1)
					.map(e => lisp(e, context)))
			: c.map(e => lisp(e, context)))
	: c }

var ns = {
	print: function(...args){
		console.log(...args) },
	add: function(...args){
		return args.reduce(
			function(res, c){
				return res + c }, 
			0) },
}

// Example...
lisp([
	['print', 'hello from lisp!', 1, ['add', 5, -3], 3],
])
