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

• Use flatten first, to convert the nested array to a flat array.
• Then pluck to get the "name" values as an array
• Finally uniq

---

_.uniq(_.pluck(_.flatten(items), "name"))

Fiddle
