push

Appends an element to the end of an array and returns a new array

(push element arr)

Returns

The push function returns a new array that includes the original elements of the input array followed by the appended element. The push! function modifies the original array and returns the value

Parameters

element (any) - the element to be added to the array.

arr (array) - the input array to which the element will be appended.

• The push function returns a new array with the appended element, leaving the original array unmodified.

• The push! function modifies the original array directly returning a value.

• Both functions are used to add elements to the end of an array.

• It is important to note the distinction between the push function, which creates a new array, and the push! function, which modifies the array in-place.

Examples

(push 5 [1, 2])
;;=> [1, 2, 5]

(def arr1 [1, 2, 3])
(push 4 arr1)
;;=> [1, 2, 3, 4]

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

(push! 5 arr1)
;;=> 5
arr1
;;=> [1, 2, 3, 5]
