My array is:

const arr = [1, 4, 8, 10, 5, 7, 5, 9, 7, 5, 44, 6]

This is how you could go about sorting your array:

const arr = [1, 5, 7, 44, 5, 9, 4, 5, 9, 10, 6, 7, 8];

const uniqueArr = arr.filter(function(item, idx, self) {
    return self.indexOf(item) == idx;
})

const sortedArr = uniqueArr.sort(function(a, b) {
    return a - b;
});
console.log(sortedArr);

const arr = [1, 4, 8, 10, 5, 7, 5, 9, 7, 5, 44, 6];
      arr.sort((a,b) => {return a - b;});
let len = arr.length;
const unique = [];

for(let i = 0; i < len; i  ){
  if(unique.indexOf(arr[i]) === -1){
     unique.push(arr[i]);
  }
}

console.log(unique);
