Factor

Factor is a programming language created by Slava Pestov in 2003. It is a concatenative, stack-based language with a powerful macro system. Factor is designed to be used both as a scripting language and as a systems programming language. TheFactor programming language is heavily inspired by the Forth programming language, and shares many features with it. However, Factor also has a number of unique features, which make it more suitable for modern programming tasks. One of the most notable features of Factor is its powerful macro system. With macros, Factor allows the programmer to extend the language in powerful ways. Factor also has excellent support for object-oriented programming, and makes it easy to create and use libraries. Factor is a very efficient language, and programs written in it are often much shorter than equivalent programs written in other languages. This makes Factor an excellent choice for writing quick scripts and small programs. Factor is an open source language, and is released under the MIT license. The Factor community is very active, and there is a large amount of helpful documentation available.
