How to Sort Numbers in an Array Numerically in Javascript

In order to sort an array of numbers ascending, use the sort function:

const array = [30, 15, 6, 8, 10, 14].sort((a,b) => a - b); //[6, 8, 10, 14, 15, 30]

Sorting an array of numbers descending, using the sort function:

const array = [30, 15, 6, 8, 10, 14].sort((a,b) => b - a); //[30, 15, 14, 10, 8, 6]

Making a copy of an array after sorting using the spread operator:

const array = [30, 15, 6, 8, 10, 14];
const sortedArray = [...array].sort((a,b) => a - b); //[6, 8, 10, 14, 15, 30]

Making a copy of an array after sorting using the slice function:

const array = [30, 15, 6, 8, 10, 14];
const sortedArray = array.slice().sort((a,b) => a - b); //[6, 8, 10, 14, 15, 30]
