Underscore: sortBy() based on multiple attributes

Question

I am trying to sort an array with objects based on multiple attributes. I.e if the first attribute is the same between two objects a second attribute should be used to comap

Answer 1

I know I'm late to the party, but I wanted to add this for those in need of a clean-er and quick-er solution that those already suggested. You can chain sortBy calls in order of least important property to most important property. In the code below I create a new array of patients sorted by Name within RoomNumber from the original array called patients.

var sortedPatients = _.chain(patients)
  .sortBy('Name')
  .sortBy('RoomNumber')
  .value();
