For example, use an object to save the state, so write:var fib = { a: 0, b: 1, n: 0, max: 5, next: function () { var r = this.a, t = this.a + this.b; this.a = this.b; this.b = t; if (this.n this.max) { this.n ++; return r; } else { return undefined; } }};It is quite tedious to use the properties of the object to save the state.Another great benefit
