reverse Method (JavaScript)

Reverses the elements in an Array.

Syntax

  
arrayObj.reverse()   

Parameters

arrayObj
Required. Any Array object.

Return Value

The reversed array.

Remarks

The required arrayObj reference is an Array object.

The reverse method reverses the elements of an Array object in place. It does not create a new Array object during execution.

If the array is not contiguous, the reverse method creates elements in the array that fill the gaps in the array. Each of these created elements has the value undefined.

Example

The following example illustrates the use of the reverse method.

var arr = new Array(0,1,2,3,4);   
var reverseArr = arr.reverse();  
document.write(reverseArr);  
  
// Output:  
// 4,3,2,1,0
