The reverse()
method reverses an array in place. The first array element becomes the last, and the last array element becomes the first.
a.reverse()
The reversed array.
The reverse
method transposes the elements of the calling array object in place, mutating the array, and returning a reference to the 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]
