Factor is dynamically [[datatype|typed]], and a unique [[Object-oriented programming|object]] system accompanies it. In Factor, there is a small group of base types, and users and the standard library can make their own classes using tuples and other mechansimsmechanisms. There is no [[Inheritance (computer science)|inheritance]], but there is [[Delegation (programming)|delegation]] as in Self. Additionally, there are other ways to make [[Class (computer science)|class]]es other than types or tuples; Factor supports [[predicate class]]es and union classes. Factor's built-in compound datatypes include fixed and variable length [[array|vector]]s and [[hash table|hashtables]]. The language also supports [[floating point]], and arbitrary precision integers. Linked lists, complex numbers and fractions are implemented in the standard library.

Factor was originally only interpreted, but it can now also be compiled. The compiler is written entirely in Factor, and it does not output standalone executables but rather merely a faster image.
