//1. sort alphabetically
/**
const countries = ["Myanmar", "Singapore", "Malaysia", "USA", "Thailand", "Vietname"];

function tnwFun1(){
    document.getElementById("demo").innerHTML = countries.join("<br />");
}

function jsSort(){
    let result = countries.sort();
    document.getElementById("demo").innerHTML = result.join("<br />");
}

function jsReverse(){
    let result = countries.reverse();
    document.getElementById("demo").innerHTML = result.join("<br />");
}

//2. Sort randomly

const tnwNums = [20, 17, 30, 38, 40, 50, 28, 12];

function tnwFun1(){
    document.getElementById("demo").innerHTML = tnwNums.join("<br />");
}

function tnwFun2(){
    let result = tnwNums.sort(tnwFun3);
    document.getElementById("demo").innerHTML = result.join("<br />");
}

function tnwFun3(a, b){
    return 0.5 - Math.random();
} */

// 3. Sort Numerically

const tnwNums = [20, 17, 30, 38, 40, 50, 28, 12, 4];

function tnwFun1(){
    document.getElementById("demo").innerHTML = tnwNums.join("<br />");
}

function jsSort(){
    let result = tnwNums.sort(function(a, b){return a - b;});
    document.getElementById("demo").innerHTML = result.join("<br />");
}

function jsReverse(){
    let result = tnwNums.sort(function(a, b){return b - a;});
    document.getElementById("demo").innerHTML = result.join("<br />");
