Check incoming data#
At times, you may want to check the incoming data. If the incoming data doesn't satisfy a condition, you may want to return a different value. For example, you want to check if a variable from the previous node is empty and return a string if it is empty. Use the following code snippet to return
not found if the variable is empty.
The above expression uses the ternary operator. You can learn more about the ternary operator here.
