JavaScript: Using Promise, async and await with HTTPRequest

Here is a small JavaScript snippet that shows how to use Promise objects, as well as async and await with HTTPRequest objects.

var net = require('net');

function download(uri)
{
    return new Promise((resolve, reject) => {
        var request = new net.HTTPRequest('GET', uri);
        var response = request.send(result => {
                if (result.error)
                    reject(result.error);
                else
                    resolve(result.response);
            }); 
    });
}

download('https://macchina.io').then(response => {
    console.log('%d %s', response.status, response.reason);
    console.log(response.contentType);
    console.log(response.content);
});

const result = (async () => {
    try 
    {
        var response = await download('https://macchina.io');
        console.log('%d %s', response.status, response.reason);
        console.log(response.contentType);
        console.log(response.content);
    }
    catch (err) 
    {
        console.log(err)
    }
})();
