Apply a named function to each member of the array. The result is a new array of the same size as the input.
let evenp x = x % 2 = 0
let result = Array.map evenp [| 1; 2; 3; 4; 5; 6 |]
The same can be done using anonymous functions, this time squaring the members of the input array.
let result = Array.map (fun x -> x * x) [|1; 2; 3; 4; 5|]
