Code :

a!localVariables(

/* Get the current year as an integer */

local!currentYear: year(now()),

/* Generate a list of the last 5 years */

local!lastFiveYears: a!forEach(

/* Enumerate creates a list of numbers {0, 1, 2, 3, 4} for the 5 years */

items: enumerate(5),

/* The expression for each item: current year minus the item index (0 through 4)

This creates the list: {2025, 2024, 2023, 2022, 2021} (assuming current year is 2025) */

expression: local!currentYear - fv!item

),

local!lastFiveYears

)

Explanation of Key Functions

now(): Returns the current date and time.
year(): Extracts the year (as an integer) from a given date.
a!localVariables(): Defines local variables to make the expression clean and readable.
enumerate(5): Creates a list of integers starting from 0 up to N-1, so enumerate(5) produces {0, 1, 2, 3, 4}.
a!forEach(): Iterates over a list (items) and applies an expression to each item (fv!item).
