JavaScript Array sort by several parameters

Array.prototype allows us to sort array just by 1 parameter. I have created my own method 'sortBy' to fix this gap. The method also allows to sort by desc. Let's say we have the following array

  
var objects = [{'Name': 'John', 'Age': 23, 'Profession': 'Accountant'},
    {'Name': 'Adam', 'Age': 18, 'Profession': 'Engineer'},
    {'Name': 'Vik', 'Age': 46, 'Profession': 'Architect'},
    {'Name': 'Jane', 'Age': 36, 'Profession': 'Developer'},
    {'Name': 'Rikky', 'Age': 28, 'Profession': 'Developer'}];

1. var objects = [{'Name': 'John', 'Age': 23, 'Profession': 'Accountant'},
2. {'Name': 'Adam', 'Age': 18, 'Profession': 'Engineer'},
3. {'Name': 'Vik', 'Age': 46, 'Profession': 'Architect'},
4. {'Name': 'Jane', 'Age': 36, 'Profession': 'Developer'},
5. {'Name': 'Rikky', 'Age': 28, 'Profession': 'Developer'}];

var objects = [{'Name': 'John', 'Age': 23, 'Profession': 'Accountant'},
    {'Name': 'Adam', 'Age': 18, 'Profession': 'Engineer'},
    {'Name': 'Vik', 'Age': 46, 'Profession': 'Architect'},
    {'Name': 'Jane', 'Age': 36, 'Profession': 'Developer'},
    {'Name': 'Rikky', 'Age': 28, 'Profession': 'Developer'}];

The following function call sorts the array by 'Profession' then by 'Name' descendantly

  
sortBy(objects, 'Profession', {'Name': 'desc'});
console.table(objects);

1. sortBy(objects, 'Profession', {'Name': 'desc'});
2. console.table(objects);

sortBy(objects, 'Profession', {'Name': 'desc'});
console.table(objects);

The result will be the following:

Now let's have a look at the method implementation.

  
var sortBy = function(arr, ...sortByArgs){
 arr.sort(function(a,b){
   var sortResult = 0;
   sortByArgs.forEach(function(arg){
     if (sortResult != 0) return;
      if(Object.values(arg)[0] == 'desc'){
        var propName = Object.keys(arg)[0];
       if (a[propName] > b[propName]){ 
       sortResult = -1;
       return;
       }
      if (a[propName] < b[propName]) {
       sortResult = 1;
        return;
       }
      }
      else {
     if (a[arg] < b[arg]){ 
       sortResult = -1;
       return;
       }
      if (a[arg] > b[arg]) {
       sortResult = 1;
        return;
       }
       }
    });
    
    return sortResult;
  });
};

1. var sortBy = function(arr, ...sortByArgs){
2. arr.sort(function(a,b){
3. var sortResult = 0;
4. sortByArgs.forEach(function(arg){
5. if (sortResult != 0) return;
6. if(Object.values(arg)[0] == 'desc'){
7. var propName = Object.keys(arg)[0];
8. if (a[propName] > b[propName]){
9. sortResult = -1;
10. return;
11. }
12. if (a[propName] < b[propName]) {
13. sortResult = 1;
14. return;
15. }
16. }
17. else {
18. if (a[arg] < b[arg]){
19. sortResult = -1;
20. return;
21. }
22. if (a[arg] > b[arg]) {
23. sortResult = 1;
24. return;
25. }
26. }
27. });
29. return sortResult;
30. });
31. };

var sortBy = function(arr, ...sortByArgs){
 arr.sort(function(a,b){
   var sortResult = 0;
   sortByArgs.forEach(function(arg){
     if (sortResult != 0) return;
      if(Object.values(arg)[0] == 'desc'){
        var propName = Object.keys(arg)[0];
       if (a[propName] > b[propName]){ 
       sortResult = -1;
       return;
       }
      if (a[propName] < b[propName]) {
       sortResult = 1;
        return;
       }
      }
      else {
     if (a[arg] < b[arg]){ 
       sortResult = -1;
       return;
       }
      if (a[arg] > b[arg]) {
       sortResult = 1;
        return;
       }
       }
    });
    
    return sortResult;
  });
};
