appointerment.appointments['16'] = '21.05.2010';

JSON is short for "JavaScript Object Notation", and as the name implies, it's basically just a way of representing Javascript objects. Thus, one can interact with JSON in the ways one tends to interact with any other object in Javascript, via the usage of the . or [] operators.

appoiterment['appointments']['16'] = '21.05.2010';

var x = { a:1, b:{c:1} }

x.b.d = 1

// x is now { a:1, b:{c:1, d:1} }

Note - But this won't work in the case of numbers like '16'.
