如何让我的程序打印 100 个随机数并以正确的方式将它们从 1 到 100 排序

Question

I got the sort and printout part of the program working, but i need to generate 100 random numbers between 1 and 100 and sort them. But I am not sure what is missing from the program to make it work correctly. I created an array to store the numbers in it and I made sure to specify the number of numbers I wanted and that it should be from 1-100.

<script>

             var arr = [];
             while(arr.length < 100){
            var r = Math.floor(Math.random() * 100) + 1;

            numbers.sort();  

            numbers.sort(function(a, b){
                return a - b;
            });
            document.write(numbers); 
            </script>

Answer 1

You had error in your while loop

var cnt = 0;
while (cnt < 100) {
  var r = Math.floor(Math.random() * 100) + 1;
  arr[cnt] = r;
  cnt++;
}

arr.sort(function(a, b) {
  return a - b;
});
document.write(arr);

Answer 2

Try

[...Array(100)].map(x=> 1+Math.random()*100|0).sort((a,b)=>a-b);

 a= [...Array(100)].map(x=> 1+Math.random()*100|0).sort((a,b)=>ab); console.log(a);

Answer 3

You can achieve this in a few lines using Array.from() method and { length: n } option like:

 const numbers = Array.from({length:100},()=>Math.floor(100*Math.random())+1); numbers.sort((a, b)=> a - b); console.log( numbers )

 .as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 4

Just modified your code, to add numbers into the array.

var numbers = [];
var i = 0;
while (i < 100) {
      var r = Math.floor(Math.random() * 100) + 1;
      numbers[i] = r;

     i++;
}
//numbers.sort();

numbers.sort(function(a, b) {
   return a - b;
});

document.write(numbers);
