fizzbuzz

[Stephen Stewart]

I was waiting for something to build last night and thought I'd have a go at Fizbuzz. It escalated real quick...

Is there a story behind this? Never 'erd of the Fizzbuzz.

[James Hughes]

For realz?  FizzBuzz is a fairly well established kata and/or interview question.

Ironically enough... I have read that article(!)

It is funny how a small problem like that could keep us entertained for hours.
Have you tried test driving it? it might take you to a whole different
set of solutions, separating the algorithm from your implementation
reqs, bringing in patterns (namespace, module), and so on.

cheers,
José

As I am a coding/javascript newcomer I first came across FizzBuzz on codeacademy. Looking forward to finding more problems like it.

[Jos Flores]

Alvyn, there's 21 similar links at the end of this post:

have fun! :)
José

[Alvyn McQuitty]

Thanks José!

[Stephen Stewart]

José,

To be test driven I'd need say, a valid string to assert against
"12fizz4buzzfizz...", to get a valid string I'd need a working
implementation, no?

We are looking for a Web Dev in my company and I sent out some interview questions that included asking them to implement FizzBuzz in JavaScript (renamed to avoid a quick google)

One answer we got back had literally an error on each line and didn't run, it was almost impressive!

Stephen, not really, your test cases can assert on a single reply to
the algorithm... and that is where your solution would be totally
changed.

You are basing your solution in the fact that you are counting from 1
to 100 (which right now is a requirement for you, and it can change),
but you are not isolating the algorithm that computes FizzBuzz, but
embedding it into that initial requirement. The solution is very
coupled (I know it's only fizzbuzz!).

If you had something like FizzBuzz.say(1), then you can assert that
the result is '1'. FizzBuzz.say(3) would expect 'Fizz'.
Your general solution would be something like a for loop to
MAX_FIZZBUZZ calling FizzBuzz.say(i) inside. Now all your pieces are
modularised and can evolve and change separately. You could even reuse
your fizzbuzz module in... well, not in many other problems I'd say :D

Is this overkill for a problem like Fizz Buzz? definitely, but are you
trying to solve fizzbuzz or are you deliberately practicing your
coding skills? that, of course, is up to you.

cheers,
José

[Stephen Stewart]

Something like this maybe?

yeah, you do have an algorithm in there. It still being declared in
the global object but you always need at least one global anyway. I
like to use namespace or module for that, in case your reqs change
again and you need more functions, but you get the idea.
Have you ever tried Jasmine? could make your life easier when coding:
http://pivotal.github.com/jasmine/
There are tons of other testing frameworks, I'm not really partial to
any, but if you use node, then jasmine-node makes it really painless
to work with Jasmine outside of the browser.

José
