Why are have you chosen to use the statement answer.indexOf(letter) != -1 instead of answer.indexOf(letter)== 0?
Why are have you chose to use the statement : answer.indexOf(letter) != -1 instead of answer.indexOf(letter)== 0?
I understand the block of code but it feels like there is a reason to it, that I don't understand yet.
answer.indexOf(letter) != -1
will evaluate as true if the character is present in the answer.
This is because the
indexOf method will return the first index of the given character. If the given character is not present, it will return
answer.indexOf(letter) == 0
will evaluate as true only if the given character has an index of 0 in the answer (meaning it is the first character).
