用js写三个数，让三个数从小到大排列

console.log('请输入三个数：');

let num1 = readline.question() - 0;

let num2 = readline.question() - 0;

let num3 = readline.question() - 0;

let num4;

if (num1 > num2) {

num4 = num1;

num1 = num2;

num2 = num4;

}

if (num2 > num3) {

num4 = num2;

num2 = num3;

num3 = num4;

}

if (num1 > num3) {

num4 = num1;

num1 = num3;

num3 = num4;

}

console.log(num1 + '<' + num2 + '<' + num3);
