sorting in javascript according to numeric value code example

Example 1: sorting array from highest to lowest javascript

// Sort an array of numbers 
let numbers = [5, 13, 1, 44, 32, 15, 500]

// Lowest to highest
let lowestToHighest = numbers.sort((a, b) => a - b);
//Output: [1,5,13,15,32,44,500]

//Highest to lowest
let highestToLowest = numbers.sort((a, b) => b-a);
//Output: [500,44,32,15,13,5,1]

Example 2: javascript sort array of ints

function sortNumbers(a, b) {
  return a - b;
}
var ages = [12, 95, 43, 15, 10, 32, 65, 78, 8];
ages.sort(sortNumbers); //ages is now sorted low to high
//console.log(ages); [8, 10, 12, 15, 32, 43, 65, 78, 95]
