pop

Retrieves a new array without the last element from an input array

(pop arr)

Returns

The function returns a new array that contains all elements of the input array except the last one.

Parameters

arr (array) - the input array from which the last element is to be excluded.

• The pop function returns a new array without the last element, while leaving the original array unmodified.

• If the input array is empty, the function will return an empty array, as there are no elements to exclude.

• The pop function does not have an in-place mutation effect on the input array. If you want to modify the array directly, you can use the pop! function instead.

Examples

(pop [1, 2, 3])
;;=> [1, 2]

(def arr1 [1, 2, 3])
(pop arr1)
;;=> [1, 2]

arr1    ;; arr1 remains the same
;;=> [1, 2, 3]

(pop! arr1)
;;=> 3
arr1
;;=> [1, 2]
