js sorting list 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: sort javascript array

var points = [40, 100, 1, 5, 25, 10];
points.sort((a,b) => a-b)

Example 3: sorting in js

var arr = [23, 34343, 1, 5, 90, 9]

//using forEach
var sortedArr = [];
arr.forEach(x => {
    if (sortedArr.length == 0)
        sortedArr.push(x)
    else {
        if (sortedArr[0] > x) sortedArr.unshift(x)
        else if (sortedArr[sortedArr.length - 1] < x) sortedArr.push(x)
        else sortedArr.splice(sortedArr.filter(y => y < x).length, 0, x)
    }
})
console.log(sortedArr);


// using sort method
console.log(arr.sort((a,b)=>{
    return a-b;
}));

Example 4: put array in alphabetical order

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.sort();
