The data type

While writing TypoScript, it is crucial to know what kind of data type you are handling. It is common to see beginners try to combine functions arbitrarily, until the anticipated result is finally achieved by accident.

The TypoScript reference is very clear about which properties exist and what their data type is, so please refer to that essential resource while developing your templates.
