sorting an array in javascript

/ Published in: JavaScript

If you need to sort an array in javascript this is how it should be done. Casting toLowerCase() is optional but but necessary if fx "Anne" was spelled "anne"

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

var arr = ["Anne", "Carl", "Benny"];
 
arr.sort(desc); //returns "Carl","Benny","Anne"
arr.sort(asc); //returns "Anne","Benny","Carl"
alert(arr);
 
function desc(a, b)
{
  if(a.toLowerCase() > b.toLowerCase()){return -1;}
  else {return 1;}
}
 
function asc(a, b)
{
  if(a.toLowerCase() < b.toLowerCase()){return -1;}
  else {return 1;}
}
