* Iterates over own and inherited enumerable properties of an object invoking

|
* `iteratee` for each property. The `iteratee` is bound to `thisArg` and invoked
|
|
* with three arguments; (value, key, object). Iterator functions may exit
|
|
* iteration early by explicitly returning `false`.

* @category Object
|
|
* @param {Object} object The object to iterate over.
|
|
* @param {Function} [iteratee=_.identity] The function invoked per iteration.
|
|
* @param {*} [thisArg] The `this` binding of `iteratee`.
|
|
* @returns {Object} Returns `object`.
|

|
|
