In this short article, we will learn how to append an item to an array?
push() method is use to add items to the end of an given array and return a new length of array. This method modifies the original Array.
You can pass more then one item in push() method. Example
const array = [1,2,3] array.push(4) console.log(array)
[ 1, 2, 3, 4 ]
The spread operator (...) allows an iterable (like array) and expands it into individual items. This method do not modify the given array and will instead returns a new array.
var newArray = [...values];
const arr1 = [1,2,3] const arr2 = [4,5,6] const newArray = [...arr1, ...arr2] console.log(newArray)
[ 1, 2, 3, 4, 5, 6 ]
