/**
|
|
* This method is like `_.find` except that it returns the key of the first
|
|
* element `predicate` returns truthy for instead of the element itself.
|
|
*
|
|
* @static
|
|
* @memberOf _
|
|
* @since 1.1.0
|
|
* @category Object
|
|
* @param {Object} object The object to inspect.
|
|
* @param {Function} [predicate=_.identity] The function invoked per iteration.
|
|
* @returns {string|undefined} Returns the key of the matched element,
|
|
* else `undefined`.
|
|
* @example
|
|
*
|
|
* var users = {
|
|
* 'barney': { 'age': 36, 'active': true },
|
|
* 'fred': { 'age': 40, 'active': false },
|
|
* 'pebbles': { 'age': 1, 'active': true }
|
|
* };
|
|
*
|
|
* _.findKey(users, function(o) { return o.age < 40; });
|
|
* // => 'barney' (iteration order is not guaranteed)
|
|
*
|
|
* // The `_.matches` iteratee shorthand.
|
|
* _.findKey(users, { 'age': 1, 'active': true });
|
|
* // => 'pebbles'
|
|
*
|
|
* // The `_.matchesProperty` iteratee shorthand.
|
|
* _.findKey(users, ['active', false]);
|
|
* // => 'fred'
|
|
*
|
|
* // The `_.property` iteratee shorthand.
|
|
* _.findKey(users, 'active');
|
|
* // => 'barney'
