Variable mapArray`Const`

mapArray: TOperation<
IMapArrayOperationData,
Omit<IMapArrayOperationData, "mapFunction">,
> = ...

Transforms each element of an array using a mapping function.

Operates on arrayData passed from previous operations. The mapFunction receives each item and optionally its index.

Returns

Operation data with mappedArray containing transformed elements

Example

// Double each number
const result = mapArray({
  arrayData: [1, 2, 3, 4],
  mapFunction: (item) => item * 2
});
// result.mappedArray = [2, 4, 6, 8]

Example

// Extract property from objects
const result = mapArray({
  arrayData: [{name: 'Alice', age: 25}, {name: 'Bob', age: 30}],
  mapFunction: (item) => item.name
});
// result.mappedArray = ['Alice', 'Bob']

Example

// Use index in transformation
const result = mapArray({
  arrayData: ['a', 'b', 'c'],
  mapFunction: (item, index) => `${index}-${item}`
});
// result.mappedArray = ['0-a', '1-b', '2-c']
