How to sort an array of objects by multiple fields

Question

From this original question  how would I apply a sort on multiple fields   Using this slightly adapted structure  how would I sort city  ascending   amp  then price  descending    var homes           h id   3         city   Dallas         state   TX         zip   75201         price   162500          h id   4         city   Bevery Hills         state   CA         zip   90210         price   319250          h id   6         city   Dallas         state   TX         zip   75000         price   556699          h id   5         city   New York         state   NY         zip   00010         price   962500            I liked the fact than an answer was given which provided a general approach   Where I plan to use this code  I will have to sort dates as well as other things   The ability to  prime  the object seemed handy  if not a little cumbersome   I ve tried to build this answer into a nice generic example  but I m not having much luck

The following function will allow you to sort an array of objects on one or multiple properties, either ascending (default) or descending on each property, and allow you to choose whether or not to perform case sensitive comparisons. By default, this function performs case insensitive sorts.

The first argument must be the array containing the objects. The subsequent argument(s) must be a comma separated list of strings that reference the different object properties to sort by. The last argument (which is optional) is a boolean to choose whether or not to perform case sensitive sorts - use true for case sensitive sorts.

The function will sort each property/key in ascending order by default. If you want a particular key to sort in descending order, then instead pass in an array in this format: ['property_name', true].

Here are some sample uses of the function followed by an explanation (where homes is an array containing the objects):

objSort(homes, 'city') --> sort by city (ascending, case in-sensitive)

objSort(homes, ['city', true]) --> sort by city (descending, case in-sensitive)

objSort(homes, 'city', true) --> sort by city then price (ascending, case sensitive)

objSort(homes, 'city', 'price') --> sort by city then price (both ascending, case in-sensitive)

objSort(homes, 'city', ['price', true]) --> sort by city (ascending) then price (descending), case in-sensitive)

And without further ado, here's the function:

function objSort() {
    var args = arguments,
        array = args[0],
        case_sensitive, keys_length, key, desc, a, b, i;

    if (typeof arguments[arguments.length - 1] === 'boolean') {
        case_sensitive = arguments[arguments.length - 1];
        keys_length = arguments.length - 1;
    } else {
        case_sensitive = false;
        keys_length = arguments.length;
    }

    return array.sort(function (obj1, obj2) {
        for (i = 1; i < keys_length; i++) {
            key = args[i];
            if (typeof key !== 'string') {
                desc = key[1];
                key = key[0];
                a = obj1[args[i][0]];
                b = obj2[args[i][0]];
            } else {
                desc = false;
                a = obj1[args[i]];
                b = obj2[args[i]];
            }

            if (case_sensitive === false && typeof a === 'string') {
                a = a.toLowerCase();
                b = b.toLowerCase();
            }

            if (! desc) {
                if (a < b) return -1;
                if (a > b) return 1;
            } else {
                if (a > b) return -1;
                if (a < b) return 1;
            }
        }
        return 0;
    });
} //end of objSort() function

And here's some sample data:

var homes = [{
    "h_id": "3",
    "city": "Dallas",
    "state": "TX",
    "zip": "75201",
    "price": 162500

Here is a generic version of  Snowburnt s solution   var sortarray     field  city   direction  asc     field  price   direction  desc     array sort function a b       for var i 0  i lt sortarray length  i             retval   a sortarray i  field   lt  b sortarray i  field    -1   a sortarray i  field   gt  b sortarray i  field    1   0          if  sortarray i  direction     desc                 retval   retval   -1                    if  retval     0                return retval                           This is based on a sort routine I m using   I didn t test this specific code so it may have errors but you get the idea   The idea is to sort based on the first field that indicates a difference and then stop and go to the next record   So  if you re sorting by three fields and the first field in the compare is enough to determine the sort order of the two records being sorted then return that sort result and go to the next record     I tested it  actually with a little more complex sort logic  on 5000 records and it did it in the blink of an eye   If you re actually loading more than 1000 records to the client you should probably be using sever-side sorting and filtering   This code isn t handling case-sensitivity but I leave it to the reader to handle this trivial modification

I was looking for something similar and ended up with this   First we have one or more sorting functions  always returning either 0  1 or -1   const sortByTitle    a  b   number   gt     a title     b title   0   a title  gt  b title   1   -1    You can create more functions for each other property you want to sort on   Then I have a function that combines these sorting functions into one   const createSorter       sorters    gt   a  b    gt    sorters reduce       d  fn    gt   d     0   fn a  b    d       0        This can be used to combine the above sorting functions in a readable way   const sorter   createSorter sortByTitle  sortByYear   items sort sorter    When a sorting function returns 0 the next sorting function will be called for further sorting

This is a complete cheat but I think that it adds value to this question because it s basically a canned library function that you can use out-of-the box   If your code has access to lodash or a lodash compatible library like underscore then you can use the   sortBy method  The snippet below is copied directly from the lodash documentation   The commented results in the examples looks like they return arrays of arrays but that s just showing the order and not the actual results which are an array of objects   var  users             user     fred         age    48           user     barney     age    36           user     fred         age    40           user     barney     age    34          sortBy users    function o      return  o user               gt   objects  for     barney    36      barney    34      fred    48      fred    40      sortBy users     user     age           gt   objects  for     barney    34      barney    36      fred    40      fred    48

Just another option  Consider to use the following utility function       Performs comparing of two items by specified properties     param   Array  props for sorting   name      value    city      -date      to set descending order on object property just add  -  at the begining of property     export const compareBy       props    gt   a  b    gt      for  let i   0  i  lt  props length  i          const ascValue   props i  startsWith  -     -1   1      const prop   props i  startsWith  -     props i  substr 1    props i       if  a prop      b prop           return a prop   gt  b prop    ascValue   -ascValue              return 0       Example of usage  in your case    homes sort compareBy  city    -price       It should be noted that this function can be even more generalized in order to be able to use nested properties like  address city  or  style size width  etc
