You can check in loop if values are different, return difference, else continue

var a=['5.5.1', '4.21.0', '4.22.0', '6.1.0', '5.1.0', '4.5.0'];

a.sort(function(a,b){
  var a1 = a.split('.');
  var b1 = b.split('.');
  var len = Math.max(a1.length, b1.length);
  
  for(var i = 0; i< len; i++){
    var _a = +a1[i] || 0;
    var _b = +b1[i] || 0;
    if(_a === _b) continue;
    else return _a > _b ? 1 : -1
  }
  return 0;
})

console.log(a)
