Outputting JSON

Big Word

Serialize: Translating an object into a format that can be stored or transferred.

JSON, CSV, XML, and others are popular. 'Deserialize' is the opposite(Converting the format back into an object).

The code

var http = require('http');
var fs = require('fs');

http.createServer(function(req, res) {

    res.writeHead(200, { 'Content-Type': 'application/json' });
    var obj = {
        firstname: 'John',
        lastname: 'Doe'
    };
    res.end(JSON.stringify(obj));

}).listen(1337, '127.0.0.1');
