Good one.

Please add random test cases in Javascript. See my updated "solution" below (I did solve the Kata correctly first.)

Thank you for exposing the need for random test cases.

BAC% = (A × (5.14 / W) × r) - .015 × H

is a less ambiguous formula description

This kata was decided to be kept.

So is the second string guaranteed to contain only letters or there may be special characters too?

This kata is a subject to a deduplication process here: https://github.com/codewars/content-issues/issues/61 .
Please join the discussion and share your opinion so duplicate kata could be identified, and then retired.

hahaha

Random tests always expect false.

Fixed it.

That test expects false in both places, the expected and actual answer were flipped, fixed it.

assertEquals(Kata.nameInStr("A crew that boards the ship", "chris"), false);

As per sample test, expected result is false. But on testing, the feedback is

expected:true but was:false

for the same.

That's cheating :(
