+
+ // objects inherit the default valueOf method of the Object object;
+ // that simply returns the itself. Since the default valueOf() method
+ // does not return a primitive value, ES next tries to convert the object
+ // to a number by calling its toString() method and converting the
+ // resulting string to a number.
+ //
+ // The toString( ) method on Array converts the array elements to strings,
+ // then returns the result of concatenating these strings, with commas in
+ // between. An array with no elements converts to the empty string, which
+ // converts to the number 0. If an array has a single element that is a
+ // number n, the array converts to a string representation of n, which is
+ // then converted back to n itself. If an array contains more than one element,
+ // or if its one element is not a number, the array converts to NaN.
