reverse

The reverse() function will reverse the items in a list.

list.reverse()

If you require reverse sorting, simply sort the list first before reversing.

[1, 5, 4, 3, 2].reverse() /* Output: [2, 3, 4, 5, 1] */

[1, 5, 4, 3, 2].sort().reverse() /* Output: [5, 4, 3, 2, 1] */
Code language: JavaScript (javascript)

Example Formulas

reverse(["Luffy", "Zoro", "Nami", "Chopper"])
/* Output: ["Chopper", "Nami", "Zoro", "Luffy"] */Code language: JavaScript (javascript)

reverse() can be useful for sorting a list of dates in reverse chronological order. Consider a Tasks relation in a Projects database. To get a list of the Last-Edited dates with the most recent first, you could write:

prop("Tasks").map(current.prop("Edited")).sort().reverse()Code language: JavaScript (javascript)

The snippet above can be found in the Latest Activity formula within Ultimate Brain, which allows for sorting views of the Projects database by the latest activity in tasks and notes connected to each project.
