/**
|
||
|
* Iterates over elements of `collection`, returning the first element
|
||
|
* `predicate` returns truthy for. The predicate is invoked with three
|
||
|
* arguments: (value, index|key, collection).

* @memberOf _
|

* @since 0.1.0
|
||
|
* @category Collection
|
||
|
* @param {Array|Object} collection The collection to inspect.
|
||
|
* @param {Function} [predicate=_.identity] The function invoked per iteration.
|
||
|
* @param {number} [fromIndex=0] The index to search from.
|
||
|
* @returns {*} Returns the matched element, else `undefined`.

* @example
|
||
|
*
|
||
|
* var users = [

*
|
||
|
* _.find(users, function(o) { return o.age < 40; });
|
||
|
* // => object for 'barney'
|
||

*
|

* // The `_.matches` iteratee shorthand.
