How to get the previous and next elements of an array loop in JavaScript?

In a simple array loop of Javacript as

for (var i=0; i<array.length; i++) {

var previous=array[i-1];
var current=array[i];
var next=array[i+1];

}

I need to get the previous and next elements in an unlimited cycle. For example,

The previous element of the first element in the array is the array last element
The next element of the last element in the array is the array first element

What can be the most efficient way to do this. The only way I can think of is to check if the element is the first or last in the array in every round.

In fact, I hope to make the array a closed cycle somehow, rather than linear.
