Your last return isn't where it should be. (And please say the language you use next time you ask for help.)

I have this problem : "Response received but no data was written to STDOUT or STDERR.", someone can help me please ? :/

• more balanced random tests
• address this issue, giving a higher probaility of lowercase letters generation

You can use a for loop. Your current solution use one but never updates status. This is why you are always returning true.

why cant i use 'for' to compelete the issue?

I'm not native English speaker and new for the Codewars. I just saw now that "ignore letter case" is correct for ignoring upper case letters. It's a synonim indeed. Sorry for my confusion. Would be better remove the comment. I put ISSUE because didn't find a label like "suggestion". Thanks guys for alerting me.

"case (in)sensitivity" is a pretty standard term, I'd get used to it

Not a kata issue, a suggestion at best.

I don't think this is an issue, "ignore letter case" means the same as "case insensitive", I don't see how this is an improvement.

Would be something like "ignore case sensitivity" instead of "ignore letter case"

so MoOse and moose would be treated the same way

Test for "moose" expects false. Test for "moOse" expects false. Relevant assertions in tests are:

assert.strictEqual( isIsogram("moose"), false );
assert.strictEqual( isIsogram("moOse"), false, "same chars may not be same case" );

Doesn't this mean they both behave the same way? What is different about them?
