Prototype - Enumerable min() Method

This method returns the minimum element (or element-based computation), or undefined if the enumeration is empty. Elements are either compared directly, or by first applying the iterator and comparing the returned values.

The optional context parameter is what the iterator function will be bound to. If used, the this keyword inside the iterator will point to the object given by the argument.



Return Value

Returns minimum value found.
