parseInt is a function.
A prototype property is automatically created for every function.
Function().prototype; //
parseInt does not have a prototype property. In order to be a Function, parseInt must have a prototype property. A function that does not have a prototype property does not conform to the Function interface; it should not be considered a function.
This applies to all built-in functions. Math.round, et c.
