- ### get(object, path, defaultValue?)
 
- ### set(object, path, value)

- #### object
 
- Type: `object`

- You are allowed to pass in `undefined` as the object to the `get` and `has` functions.
 
- #### path
 
- Type: `string`
 
- Path of the property in the object, using `.` to separate each nested key.
