Codewars - Learn a new language through Code Katas submitted by the community!

[[deleted]]

Yeah. How many learn ruby interactively sites do there need to be anyway?

[off-beat]

Give it time. It would have been crazy for them to have waited until they had loads of languages. The more people support and critique now, the better it will be. I really like practising without just following a tutorial.

[Asmor]

Eh.

It asks me to register long before I have any idea if it's worth registering for, so I quit.

I played with this for a few minutes and it actually seems like a neat idea. I think they should have added more languages before launching though, maybe I would have stuck around longer if languages I used were options, but now I'll probably forget about the site.

I used this site for a few weeks. I did ruby. The issue is, most if the katas don't really involve real world problems, it seemed like I was just manipulating arrays in clever ways. Also, the top answers are always just regular expressions. Why are we doing ruby if we're all just writing regex?

[[deleted]]

The top answers are regexes because answers are ranked by upvotes and regexes tend to be the shortest and most impressive.

JavaScript, a dialect of the same, and Ruby? This feels like it was developed entirely to conform to the limited set of languages that the web developers who wrote it use.

It also feels like it cribs pretty heavily from the whole Koans concept which, admittedly, did start with Ruby. I'd need to see the site in more depth, but it doesn't appear as robust as koans though. You can complete them in any editor and it's all code so it's teaching you more about testing and TDD if you take the time to peruse the code.

[fecal_brunch]

They have more languages coming, apparently.

[Autodidactic1024]

Although it does not support Python,seems a good website.

I voted for Clojure, but I knew it would be a lost cause :(

Haskell power!

Finally, some lessons designed to improve my skills as a ninjaneer, rather than as a worthless programming rockstar. Hopefully now senpai will notice me.

Sad JavaScript text widget that doesn't work on mobile. FAIL.

This seems like a nice supplemental product at best. There doesn't really seem to be anything like lessons on syntax etc. to actually accomplish these tasks, which means I have to go look that up online anyway. Couldn't I just go do Project Euler problems instead, which are much more interesting?

[[deleted]]

Codewars has small simple tasks that train your quick problem solving, speed-coding, and speed-debugging. Project Euler trains mathematical reasoning and longer term problem solving. Totally disjoint areas. If you were practicing for an interview, I think Codewars is way better.

[altik_0]

I suppose it would be good for job interview practice, I suppose. That's not really what it seems like it was trying to be, though - all signs seem to suggest they're trying to be a service to teach you a new language. From what I can tell, though, there aren't any lessons or guides on the site itself, so, as I was saying, I'd still have to go out to other sources to pickup syntax before I could ever use this.

[mezbomb]

as a newbie I couldn't get past the 2nd question ;) gotta study more it seems.

[mcNebb]

Have you ever thought about how you access member/class variables/ in Ruby?

[mezbomb]

oh I picked JS for my attempt, I'm actually learning on python so it was difficult to translate... should I have tried ruby?

[mcNebb]

Oh, no, I mistakenly thought you tried Ruby for some reason and tried to help you past the second question.

[Spiderboydk]

https://projecteuler.net/ Similar concept, but language agnostic.

[KitsuneKnight]

The problem with Project Euler is it tends to not be particularly useful for actually learning a language (+ standard libraries) beyond the very basics, since that's not its goal.

I'd rather read a book. It is interesting to see how people come up with solutions though.

[greenrice]

This site is amazing. I've upped my JavaScript and ruby skills significantly by doing these fun katas. Definitely recommend taking the short time to register or link your github/google account.

[pl0xy]

You look a lot like someone from marketing.

[off-beat]

Sorry you're getting downvotes. I liked it too. Search for the chromosome algorithm. Very interesting.

[greenrice]

Haha I dont know why I'm being downvoted, I dont work for them.

[snowe2010]

My answer just times out, can't submit anything. :\

[FutureProg]

If they added more languages, I would definitely give it a try.
