Underscore.js - get unique property values
javascript, json, lodash, underscore.js
Solution
_(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.)
Problem
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: ``` [ [{ "name": "Type 2", "id": 14 }], [{ "name": "Type 1", "id": 13 }, { "name": "Type 3", "id": 15 }], [{ "name": "Type 2", "id": 14 }], [{ "name": "Type 1", "id": 13 }] ] ``` to this: ``` ["Type 1","Type 2","Type 3"] ``` i.e. no duplicated and "name" property only. Any suggestions much appreciated.
