If you want to know what the custom helpers are that we ship with all components, you can open component builder. Go to the compiler and Joomla 3 then look for the helper file in the site helper file.

With a lot of place holders we customize for each component that targets that component. You'd see a Json to string method here to 'getvars'. (See video.) There's a 'getvar' singular. This is getting one variable from the database so you don't need to rewrite the whole string to get one variable.
