Not a big fan of this kata. It seems to test more math than programming skills.

• ###### Voileresolved an issue on "Scraping: Codewars Top 500 Users" kata

This isn't really a issue of the kata; but a issue of the library.

Also, why aren't people marking this thread as spoilers?

And it should not, according to the condition of the task

• ###### evgeniy_ppcommented on "Add 3 bits" kata

At first I didn't understand either. You need to sum all the arguments (they are in decimal) and convert the result to a binary as an array.

This is infamous type conversions ðŸ¤­

Oh, so there is a hack ðŸ˜†

You can see the kata's formula in this link: https://home.ubalt.edu/ntsbarsh/business-stat/otherapplets/CompoundCal.htm under Mortgage Payments Components. Used KaTeK in the description.

• ###### evgeniy_ppcommented on "Well Done Multiplus" javascript solution

Well, this is definitely bad practice ðŸ˜†. One-liners like this might impress beginners, but they are unreadable, therefore it's just bad code.

You can also write `.filter(Boolean)`.

The formula is displayed incorrectly during training. Do you think it is OK? For example, I did not even look in the "Details" before.

Check the description again.

• ###### evgeniy_ppcommented on "Calculate Monthly Mortgage Payment" kata

The formula should be `c = ( r * P0 ) / ( 1 - (1 + r) - N )`. The current formula is, even mathematically, incorrect.

• ###### Chrono79resolved an issue on "Calculate Monthly Mortgage Payment" kata

Not a kata issue.

• ###### evgeniy_ppcreated an issue for "Calculate Monthly Mortgage Payment" kata

I did not undestand the given formula for JavaScript `c = r * P0/1 - (1 + r)-N`, found another one:

``````p0 * r * (1 + r)^N
_____________________
(1 + r)^N - 1

``````

Regarding the kata, I did not like it. It is not about programming, just about math and putting correct numbers in correct spots.

Old school React class components! Well, that was fun... in a way. Firstly I rewrited everything to functions and hooks, but it turned out the test env does not know what React.useState is. Rewrited everything back again. But enjoyed it nevertheless.
