return the first non repeating character in a string in javascript

Question

So I tried looking for this in the search but the closest I could come is a similar answer in several different languages, I would like to use Javascript to do it.

Answer 1

 function FirstNotRepeatedChar(str) {
 var arr = str.split('');
 var result = '';
 var ctr = 0; 
  for (var x = 0; x < arr.length; x++) {
   ctr = 0;
  for (var y = 0; y < arr.length; y++) {
  if (arr[x] === arr[y]) {
    ctr+= 1;
    }
   }

if (ctr < 2) {
  result = arr[x];
  break;
  }
}
return result;
}
console.log(FirstNotRepeatedChar('asif shaik'));
