This is a playground to test JavaScript. It runs a completely standard copy of Node.js on a virtual server created just for you. Every one of npm’s 300,000+ packages are pre-installed, so try it out:
// We can use any package from NPM since they are all built in.
const getJSON = require("async-get-json");
// And we can use ES7 async/await to pull the ISS's position from the open API.
const dict = await getJSON("https://raw.githubusercontent.com/dwyl/english-words/master/words_dictionary.json");
const express = require("@runkit/runkit/express-endpoint/1.0.0");
const app = express(exports);
app.get("/", (req, res) => dict[req.params.name])
