| * Iterates over elements of `collection` invoking `iteratee` for each element. |
| * The `iteratee` is bound to `thisArg` and invoked with three arguments: |
| * (value, index|key, collection). Iteratee functions may exit iteration early |
| * by explicitly returning `false`. |
| * |
| * **Note:** As with other "Collections" methods, objects with a "length" property |
| * are iterated like arrays. To avoid this behavior `_.forIn` or `_.forOwn` |
| * may be used for object iteration. |
| * |

| * @alias each |
| * @category Collection |
| * @param {Array|Object|string} collection The collection to iterate over. |
| * @param {Function} [iteratee=_.identity] The function invoked per iteration. |
| * @param {*} [thisArg] The `this` binding of `iteratee`. |
| * @returns {Array|Object|string} Returns `collection`. |
| * @example |
| * |
| * _([1, 2]).forEach(function(n) { |
| * console.log(n); |
| * }).value(); |
| * // => logs each value from left to right and returns the array |
| * |
| * _.forEach({ 'a': 1, 'b': 2 }, function(n, key) { |
| * console.log(n, key); |
| * }); |
| * // => logs each value-key pair and returns the object (iteration order is not guaranteed) |
