▤ Summary

With more than two arguments, [[#FirstNotEmpty|FirstNotEmpty()]] avoids long nested [[#If|If()]] sequences that simply test for emptiness. With more than two arguments, [[#FirstNotEmpty|FirstNotEmpty()]] avoids long nested [[#If|If()]] sequences that simply test for emptiness. The functions in this section test one or more arguments to produce either a true or false outcome, and execute specific actions depending upon that result. Inverting the sense of a test can make reading expressions easier, or support better IfElse() sequences. This nested If() expression expands on the previous example, by first evaluating if the artist is Bob Dylan, and outputs if true.
