Serialization of RegExp

If somebody would be interested, there is a nice workaround. I don’t think, that current behaviour is correct. For example, Date instance is not serialized to empty object like RegExp, though it is an object and also has no JSON representation.

RegExp.prototype.toJSON = RegExp.prototype.toString;


// sample
var foo = { rgx: /qux$/ig, date: new Date }

JSON.stringify(foo);
//> {"rgx":"/qux$/gi","date":"2014-03-21T23:11:33.749Z"}"
