“Unlike mainstream component programming, scripts usually do not introduce new components but simply “wire” existing ones. Scripts can be seen as introducing behavior but no new state. /…/ Of course, there is nothing to stop a “scripting” language from introducing persistent state — it then simply turns into a normal programming language”

Clemens Szyperski, in Component Software
