/**
|
|
* Performs a deep comparison between each element in `collection` and the
|
|
* source object, returning an array of all elements that have equivalent
|
|
* property values.
|
|
*
|
|
* **Note:** This method supports comparing arrays, booleans, `Date` objects,
|
|
* numbers, `Object` objects, regexes, and strings. Objects are compared by
|
|
* their own, not inherited, enumerable properties. For comparing a single
|
|
* own or inherited property value see `_.matchesProperty`.

|
|
* @param {Array|Object|string} collection The collection to search.
|
|
* @param {Object} source The object of property values to match.
|
|
* @returns {Array} Returns the new filtered array.

|
* @example
|
|
*
|
|
* var users = [
|
|
* { 'user': 'barney', 'age': 36, 'active': false, 'pets': ['hoppy'] },
|
|
* { 'user': 'fred', 'age': 40, 'active': true, 'pets': ['baby puss', 'dino'] }
|

|
|
* _.pluck(_.where(users, { 'age': 36, 'active': false }), 'user');
|
|
* // => ['barney']
