                                    As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. In the following &quot;hello world&quot; example, many connections can be handled concurrently. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep.

const airports = 'PHX BKK OKC JFK LAX MEX EZE HEL LOS LAP LIM'.split(' ');

const routes = [

// The graph
const adjacencyList = new Map();

// Add node
function addNode(airport) {
    adjacencyList.set(airport, []);
}

// Add edge, undirected
function addEdge(origin, destination) {
    adjacencyList.get(origin).push(destination);
    adjacencyList.get(destination).push(origin);
}

// Create the Graph
airports.forEach(addNode);
routes.forEach(route =&gt; addEdge(...route))
