How To Serialize Objects

I have a data structure that is composed of an array of JavaScript objects (my own created classes) that I need to pass as a parameter to an URL:

I would like to know if there is a way to serialize this array, send it as a string, then deserialize it on the other side, resulting with the data structure again I am trying to avoid doing the serialization myself.

Each entry in the array holds an object of type Person:

function Person(name, age, children) {
this.name = name;
this.age = age;
this.children = children;
}

where children is an array of Person objects

Is this sort of thing possible?
