## summary
|
||
|
|
|
||
|
|
this module exports a function that takes 2 arguments: `options` and `defaults`. When called, it overrides all of `undefined` properties in `options` with the clones of properties defined in `defaults`
|
||
|
|
|
||
|
|
Sidecases: if called with a falsy `options` value, options will be initialized to a new object before being merged onto.
