Document or remove differences between jsesc(data, { json: true }) and JSON.stringify(data)

[mathiasbynens]

For example, jsesc doesn’t skip undefined properties, and it doesn’t make use of toJSON:

var obj = {
  'toJSON': function() {
    return 'wat';
  }
};

var x = {
  'lol': obj
};

console.log([
  JSON.stringify(x),
  jsesc(x, { 'json': true })
]);

jsesc still doesn’t skip undefined properties.
