i wanted to create a super cool thing for my website where you can run the command "node" and some sort of repl will work

attempt to mimic nodejs repl to work on browser.js

let global$1 = null;

if (typeof document !== "undefined") {
	const iframe = document.createElement("iframe");
	document.body.appendChild(iframe);
	iframe.style.display = "none";
	global$1 = iframe.contentWindow;
} else {
	global$1 = global;
}

(async function () {

	var window = this.window = undefined, self = this,
		global = this,
		exports = undefined,
		module = this.module = {}, destroy = null;



	function capitalizeFirstLetter(string) {
		return string.charAt(0).toUpperCase() + string.slice(1);
	}

	function objectStringify(object) {

		function strip(element) {
			if (typeof element === "object" || typeof element === "function") {
				return `[${capitalizeFirstLetter(typeof element)} ${element.name || element.constructor.name || key}]`
			} else if (typeof element === "string") {
				return `'${element}'`
			} else if (typeof element === "symbol") {
				return element.toString()
			} else {
				return element;
			}
		}

		if (object instanceof Promise) {
			return (async () => {
				const template = (state) => `Promise { ${state} }`
				try {

					const symbol = Symbol();
					const race = await Promise.race([object, symbol]);

					if (race === symbol) {
						return template("<pending>")
					}


					return template(typeof race === "object" ? objectStringify(race) : strip(race))
				} catch (error) {
					return template(`<rejected> ${typeof error === "object" ? objectStringify(error) : strip(error)}`)
				}

			})();
		}

		if (object instanceof Array) {
			return JSON.stringify(object)
		}

		if (object instanceof Map) {
			const { size } = object;
			return `Map(${object.size}) {${size > 3 ? "\n " : ""} ${[...object].map(([a, b]) => {
				return `${strip(a)} => ${strip(b)}`
			}).join(`, ${size > 3 ? "\n  " : ""}`)} ${size > 3 ? "\n" : ""}}`
		}

		const obj = {};
		for (const key in object) {
			const element = object[key]
			obj[key] = strip(element);
		}

		const name = object.constructor.name
		return `Object${name === "Object" ? "" : ` [${name}]`} ` + JSON.stringify(obj, null, 2).replaceAll(`"`, "")
	}

	class Test {
		number = 0
		constructor() {

		}
	}

	console.log(objectStringify({
		test: "hewo",
		arrow: () => { },
		function: function name() { },
		obj: {},
		symbol: Symbol("test"),
		boolean: !0,
		number: 0
	}))

	console.log(global.eval("const testo = false; testo"))

}).call(global$1)
