JavaScript - move element of array to the last position

In this article, we would like to show you how to move an element of an array to the last position in JavaScript.

1. By index

In the below examples, we move the element at the index position to the end of the array.

// ONLINE-RUNNER:browser;

const array = ['a', 'd', 'b', 'c'];

const index = 1;

array.push(array.splice(index, 1)[0]);

console.log(array); // [ 'a', 'b', 'c', 'd' ]

2. By value

In the below examples, we search for the value in array and move it to the last position.

// ONLINE-RUNNER:browser;

const array = ['a', 'd', 'b', 'c'];

const value = 'd';

array.push(array.splice(array.indexOf(value), 1)[0]);

console.log(array); // [ 'a', 'b', 'c', 'd' ]
