What does the 'map' method do on an array in Avaloq Script?

• A. It filters the elements of an array
• B. It transforms each element of an array
• C. It sorts the array elements
• D. It finds the maximum value in an array

Answer: (B)

The 'map' method in Avaloq Script serves a specific purpose of transforming each element of an array. When you utilize the 'map' method, you provide a callback function that is applied to each element of the array, allowing you to produce a new array where each element is the result of the transformation specified in that callback function. This approach enables you to create modified versions of data efficiently without changing the original array, as 'map' generates a new array with the transformed values. This functionality is particularly useful in scenarios where you wish to apply a consistent operation to all elements, such as converting data types, modifying values, or extracting certain properties from complex objects. The key characteristic of 'map' is that it does not filter or sort the array, nor does it perform operations like finding maximum values; rather, it focuses solely on transforming each individual element.
