 ### Constructed object usage

 ### Alternative property names
 
-If your directory contains files where the names do not match what you want in the resulting property (for example, you want camelCase but the file names are snake_case), then you can use the `map` function. The `map` function is called on both file and directory names, as they are added to the resulting object.

 ### Filtering files
 
-If your directory contains files that you do not want to require, or that you want only a part of the file's name to be used as the property name, `filter` can be a regular expression. In the following example, the `filter` is set to `/^(.+Controller)\.js$/`, which means only files that end in "Conroller.js" are required, and the resulting property name will be the name of the file without the ".js" extension. For example, the file "MainController.js" will match, and since the first capture group will contain "MainController", that will be the property name used.

-For even more advanced usage, the `filter` option also accepts a function that is invoked with the file name as the first argument. The filter function is expected to return a falsy value to ignore the file, otherwise a string to use as the property name.
