reverse

Use reverse to reverse the order of specified elements in a list.

Basic syntax

To reverse a specified list of elements, use the following syntax:

(reverse [elements])

Arguments

Use the following argument to specify the elements to be reversed using the reverse Pact function.

Argument	Type	Description
elements	[any]	Specifies the elements in the list you want to be reversed.

Return value

The reverse function returns a new list with the elements in reverse order.

Example

The following example demonstrates how to use the reverse function in the Pact REPL. This example reverses the order of numbers in the list:

pact> (reverse [1 2 3])
[3 2 1]

In the following example, the reverse function reverses the order of strings in a list:

pact> (reverse ["lastname" "firstname" "age" "occupation"])
["occupation" "age" "firstname" "lastname"]

You can also reverse the order of objects in a list. For example:

(reverse [{"lastname":"pistolas","firstname": "lola"} {"lastname":"smith","firstname": "tim"}])
[{"lastname": "smith","firstname": "tim"}
{"lastname": "pistolas","firstname": "lola"}]

This example illustrates how to use the reverse function to reverse the order of elements in a list in Pact.
