* @category Collection
* @param {Array|Object|string} collection The collection to search.
* @param {Function|Object|string} [predicate=_.identity] The function invoked
* per iteration.
* @param {*} [thisArg] The `this` binding of `predicate`.
* @returns {*} Returns the matched element, else `undefined`.
