Syntax

a.reverse()

Dönen Değer

The reversed array.

Açıklama

reverse metodu dizinin olduğu halini kalıcı olarak değistirir ve değiştirilmiş diziyi döndürür.

reverse is intentionally generic; this method can be called or applied to objects resembling arrays. Objects which do not contain a length property reflecting the last in a series of consecutive, zero-based numerical properties may not behave in any meaningful manner.

Examples

Reversing the elements in an array

The following example creates an array a, containing three elements, then reverses the array. The call to reverse() returns a reference to the reversed array a.

const a = [1, 2, 3];

console.log(a); // [1, 2, 3]

a.reverse(); 

console.log(a); // [3, 2, 1]

Reversing the elements in an array-like object

The following example creates an array-like object a, containing three elements and a length property, then reverses the array-like object. The call to reverse() returns a reference to the reversed array-like object a.

const a = {0: 1, 1: 2, 2: 3, length: 3};

console.log(a); // {0: 1, 1: 2, 2: 3, length: 3}

Array.prototype.reverse.call(a); //same syntax for using apply()

console.log(a); // {0: 3, 1: 2, 2: 1, length: 3}
