			METHOD: Function::valueOf Function.valueOf () The valueOf method returns a string which represents the source code of a function. This over-rides the Object.valueOf method. The valueOf method is usually called by JavaScript behind the scenes, but to demonstrate the output, the following code first creates a Function object called Car, and then displays the value of that function: Code: function car(make, model, year) {this.make = make, this.model = model, this.year = year} document.write(car.valueOf()) Output: function car(make, model, year) {this.make = make, this.model = model, this.year = year With the built-in Function object the valueOf method would produce the following string: Output: function Function() { [native code] }.
