I am new to JavaScript, and I have an array which contains numbers.

 var arr = [2,4,8,1,5,9,3,7,6];

How can I sort it using a native for loop in JavaScript?

I know sort function is available, but I want it through for loop.

The output should be:

 var res = [1,2,3,4,5,6,7,8,9];

I would do something like this...

var input = [2,3,8,1,4,5,9,7,6];



var output = [];

var inserted;



for (var i = 0, ii = input.length ; i < ii ; i++){

  inserted = false;

  for (var j = 0, jj = output.length ; j < jj ; j++){

    if (input[i] < output[j]){

      inserted = true;

      output.splice(j, 0, input[i]);

      break;

    }

  }



  if (!inserted)

    output.push(input[i])

}



console.log(output);

Maybe there are more efficient ways, but if you want to use the for loop, it's my first idea...
