js reverse sort 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: array reverse algorithm in js

let array1 = ["yes", "no", "maybe", "always", "sometimes", "never", "if"];
let array2 = [5,8,2,9,5,6,3,1];

function reverseArray(arr) {
  var newArray = [];
  for (var i = arr.length - 1; i >= 0; i--) {
    newArray.push(arr[i]);
  }
  return newArray;
}

reverseArray(array1); // ["if", "never", "sometimes", "always", "maybe", "no", "yes"]
reverseArray(array2); // [1, 3, 6, 5, 9, 2, 8, 5]

Example 3: javascript sort array in ascending order

//sorts arrays of numbers
function myFunction() {
  points.sort(function(a, b){return a-b});
  document.getElementById("demo").innerHTML = points;
}

Example 4: javascript sort descending

function sortEggsInNest(a, b) {
  return a > b ? -1 : b > a ? 1 : 0;
}

Example 5: string sort javascript

var names = ["Peter", "Emma", "Jack", "Mia"];
var sorted = names.sort(); // ["Emma", "Jack", "Mia", "Peter"]
