Added check that options is an object

[rhinoceraptor]

The motivation for this is that humps' functions may be used as a callback in a map, forEach (or similar), and if the second argument is not an object, the 'process' in options ? ... check will throw an error.

Thanks for this. In this case, is there any harm in a wrapping the converter in a function?

Do you mean the difference between these two?

myArray.map(humps.camelize)

vs

myArray.map(i => humps.camelize(i))

If so, the only real reason is syntactic convenience.
