Is there some handy way of defining direction per column    No  You cannot specify the sort order other than by a callback function that inverses the value  Not even this is possible for a multicolumn sort   You might be able to do     each array of objects  function o         o typeDesc   -o type     assuming a number         sortBy array of objects    typeDesc    name      For everything else  you will need to resort to the native  sort   with a custom comparison function    array of objects sort function a  b         return a type - b type    asc               b name gt a name   - a name gt b name     desc

It s worth noting that if you want to sort particular properties descending  you don t want to simply append  reverse   at the end  as this will make all of the sorts descending   To make particular sorts descending  chain your sorts from least significant to most significant  calling  reverse   after each sort that you want to be descending   var data     data  chain        sort  date        reverse         sort by date descending      sort  name      sort by name ascending      result     Since   s sort is a stable sort  you can safely chain and reverse sorts because if two items have the same value for a property  their order is preserved   More information
