Write input to the Log panel.
Logs a formatted string to the log window, letting you replace {{input name}} with any input value.
Converts any input type to a String. This function is not suitable for serialization; use for example Json.Stringify instead.

Count can be used to make tranditional for-loops. The on count trigger will execute `iterations` number of times. The donetrigger will execute when the loop is completed. The reset input trigger is used to start the loop.
For can be used to make a traditional for-each-loop. The on count trigger will execute once per item in the items input, which expects a list.
