The arr.sort() method is used to sort the array in place in a given order according to the compare() function. If the method is omitted then the array is sorted in ascending order.

Syntax:


arr.sort(compareFunction)


Parameters: This method accept a single parameter as mentioned above and described below:


    

  • compareFunction: This parameters is used to sort the elements according to different attributes and in the different order.

      

    • compareFunction(a,b) < 0
      • 

      Then a comes before b in the answer.
      

    • compareFunction(a,b) > 0
      • 

      Then b comes before a in the answer.


      

    • compareFunction(a,b) = 0
      • 

      Then the order of a and b remains unchanged.

    

    • 



Return value: This method returns the reference of the sorted original array.


Below examples illustrate the JavaScript Array sort() method:


  • Example 1: In this example the sort() method arranges the elements of the array in ascending order.

    var arr = [2, 5, 8, 1, 4]
document.write(arr.sort());
document.write(arr);

    

    Output:
    

    1,2,4,5,8
1,2,4,5,8

    

    • 

  • Example 2: In this example the sort() method the elements of the array are sorted according the function applied on each element.

    var arr = [2, 5, 8, 1, 4]
document.write(arr.sort(function(a, b) {
  return a + 2 * b;
}));
document.write(arr);

    

    Output:
    

    2,5,8,1,4
2,5,8,1,4
