For more advanced users, the Qlik Sense script provides the capability to programmatically extract and transform data from data sources.

Most users will use the Data manager, but it is important to note that this capability exists for users who need to transform data in more complex ways:

The preceding screenshot is of the Qlik Sense script setting a variable with the Today() function and loading a table from a QVD, which is a proprietary Qlik data file that is optimized for use in Qlik. Most users will not leverage QVDs directly, but there are many advanced use cases where they can and should be leveraged.
