isReactive

Returns true if the given value was created or extended by mobservable. Optionally accepts a second string parameter to see whether a specific property is observable.

var person = makeReactive({
    firstName: "Sherlock",
    lastName: "Holmes"
});
person.age = 3;
isReactive(person); // true
isReactive(person, "firstName"); // true
isReactive(person.firstName); // false (just a string)
isReactive(person, "age"); // false
