Question

I read in the EcmaScript specification that certain methods are "generic". What does this mean?

Does it mean that the methods make little or no assumptions about the object bound to the this value when the function is invoked?

Answer 1

In Object-Oriented Programming, a generic function is a function that uses the types of its arguments to automatically run the most appropriate method. From the EcmaScript draft:

Generic functions are function objects each with a set of attached methods. A call to a generic function matches the types of the actual arguments to the signatures of the attached methods and dispatches to the most appropriate method following deterministic rules.
