Nice work translating Adagrams to Javascript! Let me know if you have questions on any feedback =]

This loop declares a variable i, but we never use that variable inside the loop. A while loop that runs until the hand array has 10 elements might be a better fit.

This implementation has an O(n^2) time complexity, how could we use a frequency map to bring the time complexity down to O(n)?

Nice use of the spread operator to copy lettersInHand!

Love a good ternary expression ^_^
I would recommend removing the comment at the end or reframing it to describe the purpose of this ternary expression.
