ArrayMap

Takes an array and executes the function declared in the Mapper field for each of its elements, returning a new array containing the results. The output array preserves the same order and length as the input array.

Reference

Parameters

array

The array whose elements the mapper will be applied to.

Component data2-core-types@Getter

mapper

The function applied to each element. It expects a Function component, with an Arguments field declaring a key to reference each item during iteration (e.g. number). The key can then be used inside the function body via a Reference component, which dynamically resolves to the value of the current element at each iteration.

Component data2-core-functions@Function

Example

Input

[1, 2, 3, 4, 5]

Arguments key: number

Mapper:

• Function: Multiply
  • Components:
    • Reference: number
    • 2

Output:

[2, 4, 6, 8, 10]

Note: The output array will always have the same number of elements as the input array. Each position in the output corresponds directly to the result of the function applied to the element at the same position in the input.
