MAP

MAP(array1, [array2,] lambda)

Returns the array formed by applying a map using a LAMBDA function.

array1	An array to be mapped.
array2	(Optional) Another array to be mapped.
lambda	A nested LAMBDA function that takes either a single array or two array parameters.

REMARKS

* This function was added in Excel 2024.
* This function can create a Dynamic Array Formula.
* This function uses the LAMBDA function.
* The LAMBDA function must be the last argument.
* The LAMBDA function must have a parameter for each array.
* You can use the REDUCE function to return a single value after applying a LAMBDA function to an array.
* You can use the SCAN function to return an identical array by applying a LAMBDA function to return some intermediate calculation values.
* This function was first released in July 2021.

1	=MAP(10, LAMBDA(p_one, IF(p_one>5, p_one*p_one, p_one))) = 100
2	=MAP(5, LAMBDA(p_one, IF(p_one>5, p_one*p_one, p_one))) = 5
3	=MAP({5,10},LAMBDA(p_one,IF(p_one>5, p_one*p_one, p_one))) = {5,100}

1 - We would like to square all the numbers in the array that are greater than 5.
2 - We would like to square all the numbers in the array that are greater than 5.
3 - We would like to square all the numbers in the array that are greater than 5.
