A web service provides the following array named "Colors":Which expression returns the first ID in...

Understanding the Array and the Task:

Input Array (Colors):

[

{ "ID": "22342", "name": "Red" },

{ "ID": "33495", "name": "Blue" }

]

Goal: Extract the first ID from the array, which is "22342".

Why Option B is Correct:

The expressionget(map(2.Colors; ID); 1):

map(2.Colors; ID): Iterates over the array 2.Colors and extracts the ID field from each object. This creates a new array containing just the IDs:["22342", "33495"].

get(...; 1): Retrieves the first element of the newly created array, which is "22342".

Why the Other Options are Incorrect:

Option A (map(2.Colors; ID; ID; 1)):

This syntax is invalid because the additional ID and 1 parameters are misplaced. The map function requires only two arguments: the array and the field to map.

Option C (map(get(2.Colors; ID); 1)):

This incorrectly attempts to use get inside map. The get function does not return a field for mapping, so the syntax is invalid.

How the Expression Works:

Step 1: map(2.Colors; ID)

Extracts the ID field from each object in the Colors array.

Output: ["22342", "33495"].

Step 2: get(...; 1)

Retrieves the first element of the mapped array.

Output: "22342".

Use Case in Workfront Fusion:

This approach is commonly used when processing arrays in Fusion scenarios, ensuring specific elements are accessed without additional looping or complex logic.

By combining map and get, this expression efficiently extracts the first ID from the array, ensuring correct and reliable results.
