This part is the same as writing 'a'++ and that returns “NaN” (short for “not a number”) since you can’t increment a character, but this return type is a string, so the interpreter just concatenates it with the other letters: baNaNa. Then that string is converted to lower case to give the final result, “banana”.
Returns “banana”

Yep, I believe you’re right
