What is the fastest way to move an element from the beginning of an array to the end in JavaScript?

For example, if we have:

var array = [5,1,2,3,4];

and the result I want is:

var array = [1,2,3,4,5];

Just combine shift() and push() methods:

shift() method removes the first element from an array and returns that removed element,
push() method adds the element at the end of the array.

Practical example

// ONLINE-RUNNER:browser;

var array = [5, 1, 2, 3, 4];

array.push(array.shift());

console.log(array); // [ 1, 2, 3, 4, 5 ]

Note:

If you want to move any element to the first/last position check out the See also section below.
