Thank you for the changes and prompt reply!

I changed the tests to give a somewhat bettwer feedback, but infortunately your solution fails only for longer inputs so it can be not that easy to debug. However, I found out that your solution fails following test case:

assert.strictEqual(nameInStr('Betty', 'Betty'), true);

Additionally, you are handling letter case incorrectly: "case-insensitive" means that lowercase letters and uppercase letters should be treated as the same.

Yoru solution is buggy, it's not a kata issue.

From Output:

Expected: true, instead got: false

[ 'ocll tottcnydlj yxp yajneqiybj axeeberr y kyttidbirsiyem hmjjlrijr jalci ii ts r',
'Alexandria' ]

Sorry, I don't understand why we should end up with "true".

"Letter comparison should be case-INsensitive."

And there is no "A" in the "str".

And even if we forget about letter case, the letters are not in the right order:

'ocll tottcnydlj yxp yAjneqiybj axeeberr y kyttidbirsiyem hmjjLrijr jalci ii ts r'
