Obviously TypoScript is not a normal programming or scripting language, and yet is very powerful. So how do we ultimately classify TypoScript? TypoScript can be used to configure TYPO3; it can thus be described as a configuration language for which no programming knowledge is necessary. In contrast to true programming or scripting languages, TypoScript lacks elements (such as loops) that are typical of such languages. In fact, TypoScript consists of configuration instructions that are incredibly simple in structure and are reminiscent of CSS in their simplicity (with respect to their syntax and not the effect).
How TypoScript is structured can be seen with the help of the TypoScript Object Browser tool. For this, go to Web | Template and select the TypoScript Object Browser menu from the drop-down list.
Here you can see the TypoScript objects in a clear tree structure. You will learn more about the TypoScript Object Browser and the objects on the following pages.
