Your function doesn't return the correct result. It adds an extra space at the end.

"The quick brown fox jumps over the lazy dog.": expected 'ehT kciuq nworb xof spmuj revo eht yzal .god ' to equal 'ehT kciuq nworb xof spmuj revo eht yzal .god'

Even if you fix that, your solution also does not handle words with double spaces correctly either (as in the 4th sample test).

You checked it wrong:

Input:   "The quick brown fox jumps over the lazy dog.": 
expected 'ehT kciuq nworb xof spmuj revo eht yzal .god ' 
to equal 'ehT kciuq nworb xof spmuj revo eht yzal .god'
                                                      ^ here your solution is different 

i'm using Javascript. first time reporting this. i did check if result matched with expect result

You need to tell us what language you tried, and show us your code. Otherwise, we do not know what to fix.

still broken sadly i had correct solution but was not right when expect out put was same as result output

Like which one? In which language?

The given solutions do not work, im not sure why? Is it because the kata changed?

There are several problems with your code, about the indentation one, you know that in Python you should indent your code right? Then why is words at the same level as def line?

Give me please a little hint how do i reverse words but still have the spaces

What is it that you don't understand? You have to reverse every single word in its place in the string.

I dont understand it at all, it's too hard for 7 kyu
