Script blocks use a simple procedural language enclosed inside of UJML script or eval elements. See script, eval. Unlike everything else in UJML, this scripting language is not based on XML; instead it resembles a subset of JavaScript (also known as ECMAScript because it is a standard of Ecma International). It has a clean syntax with a small set of keywords and operators which you can combine into complex and powerful scripting statements. See Scripting Language. 

Script blocks using the script element are the preferred method of scripting in UJML. See script. In this documentation, all examples are created using this scripting language.
