 function uniq(a) {
    return a.sort().filter(function(v, i, a) {
      return !i || v != a[i - 1];
    });
 }

 Got a smart way

 function uniq(arr) {
  return arr.filter((v,i,a) => a.indexOf(v)===i);
 }
	function uniq(a) {
	return a.sort().filter(function(v, i, a) {
	return !i \|\| v != a[i - 1];
	});
	}
