Hi davidhuckfield,

There is something else to consider: your kata is subject to the beta process. And a task like this has close to 0 chances to survive the beta phase, because, even if it's not an exact duplicate, beta testers will (rightfully) recognize it as so and the kata will get "not satisfied" votes, leading to its retirement anyway.

I understand this is very frustrating for you, considering you already poured work into your kata, but I'd suggest you revise your opinion/point of view on the topic. Otherwise you might just succeed at increasing your frustration level with the platform.

Cheers

Note: it is very doubtfull there aren't any kata around doing the exact same thing. But as said above, it's almost impossible to find duplicates in the database...

There are already hundreds (if not thousands) of easy tasks. This is plenty enough to cover such a kind of thing. The database doesn't need more of them, even if well done and with enthusiasm. ;)

My point is, I've found a few katas that filter arrays, or arrays of arrays, but none that filter arrays of objects. Is it not a worthwhile exercise for those new to coding (as most of those doing 8 kyu katas will be) to learn that you can perform the same actions on an array of objects? It also allows them to access the .type of each object and thereby provides something new compared to any of the supposed duplicates that have been linked.

I've not found any katas that do quite what this one does, which is the reason I wrote it. Again I really don't see how this is a duplicate, and if it's similar to other katas well then half the katas on this site are similar in one way or another. If it's because it's a simple sorting or mapping task, again many beginner katas are of this type.

If anyone has any ideas as to how they think I should change this then I'm open to suggestions, but I don't just want to make it more complicated because that defeats the point. There's no point my sharing this with fellow students if I'm forced to make it more complex for the sake of novelty when it already appears to not be a duplicate of any existing kata.

The Coding Meetup series is relevant here, in particular #12, 15, #16, and maybe others.

So if it's not an exact duplicate, what's the problem here exactly?

An exact duplicate is not required for an idea to be considered duplicate or not novel. Yes, there exist approved duplicates, and you can see here the work that is being done in order to address that.

So if it's not an exact duplicate, what's the problem here exactly? I've seen the three other similar problems which all involve sorting/filtering an array or an array of arrays, not an array of objects. I'm not being passive aggressive, I'm trying to be as polite and constructive as possible and you don't really seem to be attempting to help or provide any kind of suggestion here. I get that you want to prevent duplicates but I'm not actually seeing one here. I'm sure to you this is very simple and boring but try to be a bit more welcoming to new learners and not just shut people down because you don't find it interesting. I've seen about 10 nearly identical "Hello World" katas but I'm not on their comments berating them about it.

sure, if you want an exact duplicate, good luck finding it in the ocean of kata's

Those aren't filtering objects by a property as in this kata. I'm 97% sure I've seen a JS object filter challenge somewhere though...

• First hit I find on searching for "filter": https://www.codewars.com/kata/53dbd5315a3c69eed20002dd/javascript

This does seem likely to be a dupe but I wasn't able to find anything obvious after poking around for a minute. If we can find a concrete dupe, that should bring some clarity to the discussion here.

Again, passive aggressive attitude at full display, "mate". Don't expect much help from me in the future.

Mate I don't know what to say to you at this point, when you start assisting me let me know and I'll take on board whatever you have to say. So far you've given me nothing I can work with.

With that attitude you make it hard for me to assist you.

Your initial comment was just "this is trivial and a duplicate". No info about which other kata you think it's similar to, no advice for improvement. For an 8 kyu kata made by someone who started learning JS 3 weeks ago i think the quality is just fine, but like i said I'm open to any constructive criticism that doesn't amount to "this sucks and it shouldn't exist".

Already read them and didn't find any existing ones using filter on objects. By all means let me know if there are similar ones, but your tone is unnecessarily rude to someone who is new to coding and is just trying to learn. Try leaving some constructive feedback instead of being patronising.

first paragraph:

Make sure your kata adds some new value to Codewars. Avoid creating blatant duplicates, and use the idea which has not yet been widely used to create a kata. Note that with so many existing kata, this can be very challenging to achieve, because it's very difficult to find out if your idea has already been used or not. Remember that you can always ask more experienced users if your idea is worthy of creating a new kata, or maybe it has been already exploited sufficiently.

What I expect from YOU is that you read the guidelines: https://docs.codewars.com/authoring/guidelines/kata.
