* Iterates over elements of collection, returning the first element

*
* @param collection - The collection to inspect
* @param predicate - The function invoked per iteration
* @param fromIndex - The index to search from
* @returns The matched element, else undefined
*
* @example
* ```ts
* const users = [

* { 'user': 'fred', 'age': 40, 'active': false },
* { 'user': 'pebbles', 'age': 1, 'active': true }

* // => 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.
