List.Sort
List.Sort(list as list, optional comparisonCriteria as any) as list
Sorts a list of data, list
, according to the optional criteria specified. An optional parameter, comparisonCriteria
, can be specified as the comparison criterion. This can take the following values:
To control the order, the comparison criterion can be an Order enum value. (Order.Descending, Order.Ascending).
To compute a key to be used for sorting, a function of 1 argument can be used.
To both select a key and control order, comparison criterion can be a list containing the key and order (
{each 1 / _, Order.Descending}
).To completely control the comparison, a function of 2 arguments can be used. This function will be passed two items from the list (any two items, in any order). The function should return one of the following values:
-1
: The first item is less than the second item.0
: The items are equal.1
: The first item is greater than the second item.
Value.Compare is a method that can be used to delegate this logic.
Sort the list {2, 3, 1}.
Usage
List.Sort({2, 3, 1})
Output
{1, 2, 3}
Sort the list {2, 3, 1} in descending order.
Usage
List.Sort({2, 3, 1}, Order.Descending)
Output
{3, 2, 1}
Sort the list {2, 3, 1} in descending order using the Value.Compare method.
Usage
List.Sort({2, 3, 1}, (x, y) => Value.Compare(1/x, 1/y))
Output
{3, 2, 1}
