Underscore.js - get unique property values

Question

I only recently discovered the power of underscore.js, still new to the methods I kindly ask for a suggestion:

How do I get from this:

[
    [{
                 


        

Answer 1

_(data).chain().flatten().pluck('name').unique().value()

(Convert the nested lists to a flat one, pick name from each of the objects in the list, and make it unique.)
