How To: Kinetic Row Rule Functions

This one is a pretty short tutorial, but has the potential to allow for greater control over the rules you use in App Studio.

You can use JavaScript functions and expressions to do more complex Row Rules in App Studio, however, they are a tad finicky in their current iteration, so it may take some playing in order to get it to time just right.

Row Rules fire initially on form load, so you need to check for undefined in order for it to not blow up when the screen loads.
YourColumn === undefined or YourColumn !== undefined

The syntax would be:

return ( <Null Check> || <Expression or Function> )

return (ABCCode === undefined || ABCCode.includes('A'))
