/** |
|
* Iterates over elements of `collection`, returning the first element |
|
* `predicate` returns truthy for. The predicate is invoked with three |
|
* arguments: (value, index|key, collection). |
|
* |
|
* @static |
|
* @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 = [ |
|
* { 'user': 'barney', 'age': 36, 'active': true }, |
|
* { 'user': 'fred', 'age': 40, 'active': false }, |
|
* { 'user': 'pebbles', 'age': 1, 'active': true } |
|
* ]; |
|
* |
|
* _.find(users, function(o) { return o.age < 40; }); |
|
* // => object for 'barney' |
|
* |
|
* // The `_.matches` iteratee shorthand. |
|
* _.find(users, { 'age': 1, 'active': true }); |
|
* // => object for 'pebbles' |
|
* |
|
* // The `_.matchesProperty` iteratee shorthand. |
|
* _.find(users, ['active', false]); |
|
* // => object for 'fred' |
|
* |
|
* // The `_.property` iteratee shorthand. |
|
* _.find(users, 'active'); |
