WHat is the input format ? Consists of only lowercase letters or any kind of characters? Do space separated palindromes or palindromes formed using mixed case letters count ?
for ex : In string "I coulD am madl bb" , which is largest palindrome substring "lD am madl", "am ma" or "bb"

Kata description says that it expects a hash value as output , however in JS it expects an object literal and not a map .

roughly 10-20% more efficient from random tests

Whats strange is y==alphabeth[i] outperformed y===alphabeth[i]
Nothing significant, just 3-5% in favor of ==, but I would have suspected the opposite

assertSimilar is deprecated, use assertDeepEquals

getting this error in js

sum of cubes is div by 3 iff sum is div by 3.

Sorting is not best practice.

nice solution. JS makes it unnecessarily complicated to work with ASCII codes of alphabets, so i find the criticism of manual shifting misplaced.
