Globals are the main components of Helium Scraper. They are composed of statements and function calls, usually wrapped in a do-block statement. Typically, a do-block statement with an extract statement as the last element will be used as an extraction statement. When such a global is evaluated by pressing the Play button on the global editor, a set of output tables will be created on the database named after the global. Globals can also be used to define functions and values.
