Understanding the Expression:

The provided expression uses the ifempty function:

ifempty(2.data:types[]; "No Type")

Structure of the Expression:

The first parameter, 2.data:types[], is an array being checked for content.

The second parameter, "No Type", is the fallback value returned if the array is empty or undefined.

Purpose of ifempty: This function checks if the given value is empty or undefined. If the value is not empty, it returns the value. If the value is empty, it returns the fallback text ("No Type").

Expected Module Outputs:

A. Non-empty array:

If 2.data:types[] is a non-empty array, the function returns the array as-is.

C. Text value 'No Type':

If 2.data:types[] is empty or undefined, the function returns the fallback text value "No Type".

Why the Other Options are Incorrect:

Option B ("An empty field"):

The ifempty function does not return an empty field. If the value is empty, it substitutes it with the fallback text ("No Type").

Option D ("Collections comma separated"):

The function operates on arrays, but it does not format the output as comma-separated collections. The raw array is returned if non-empty.

Key Use Cases:

This type of function is frequently used in Workfront Fusion to handle situations where data might be missing or incomplete, ensuring scenarios continue to run smoothly without errors caused by undefined or empty fields.

Example Outputs:

If 2.data:types[] = ["Type1", "Type2"]: The function returns ["Type1", "Type2"].

If 2.data:types[] = [] or undefined: The function returns "No Type".
