What it does
True when a text is blank or a list has nothing in it. It's a value node: no white pins, it works out its answer when a step wired to it needs it. It gives 1 value later steps can use. Find it under Logic in the palette.
When to use it
Use it to decide what happens next: true when a text is blank or a list has nothing in it.
