## For bonus points
|
||||
|
||||
Did you get the tests passing and the code clean? If you want to, these
|
||||
are some additional things you could try:
|
||||
|
||||
* Remove as much duplication as you possibly can.
|
||||
* Optimize for readability, even if it means introducing duplication.
|
||||
* If you've removed all the duplication, do you have a lot of
|
||||
conditionals? Try replacing the conditionals with polymorphism, if it
|
||||
applies in this language. How readable is it?
|
||||
|
||||
Then please share your thoughts in a comment on the submission. Did this
|
||||
experiment make the code better? Worse? Did you learn anything from it?
