make array out of sub array js code example

Example 1: javascript how to get subarray

const ar  = [1, 2, 3, 4, 5];

// slice from 1..3 - add 1 as the end index is not included

const ar2 = ar.slice(1, 3 + 1);

console.log(ar2);

Example 2: js copy part of array

// The slice function copies parts of an array and 
// do therefore not change the default array

let arr = ["apple", "kiwi", "banana", "pear"];

let newArray = arr.slice(1, 2)

console.log(newArray); // output : kiwi
