<p>Factor belongs to the family of <em><a href="http://concatenative.org/wiki/view/Concatenative%20language">concatenative languages</a></em>: this means that, at the lowest level, a Factor program is a series of words (functions) that manipulate a stack of references to dynamically-typed values. This gives the language a powerful foundation which allows many abstractions and paradigms to be built on top. Reload this page to see a random code example below.</p>
