QUESTION
Apologize upfront, I am very new to JS. Having trouble finding out where I should put the arrow function here for this question. I've tried putting it in the parameters when I call the function but that seems very wrong. Exact question is: Call the processSplicedValue function again, but this time pass in an anonymous arrow function that alerts the spliced value.

QUESTION
I am trying to have an array be searched for a string by using a For loop, going through each spot of the array for its length. If the string is present, it should show that string (in this case, a letter). For some reason, even when that letter is there, the output is not being updated.
For example, say the word is DOG. The output array would look like '▢ ▢ ▢'. If I guessed 'D', it should update the output array to be 'D ▢ ▢'. The problem here is, it is not doing that.
This is my code related to this part:
...ANSWER
Answered 2020-Dec-07 at 15:13String comparisons are case sensitive. That means that the letter "e" is different from the letter "E". In your code, you are saying that the letter being guessed is a vowel if it's equal to "a", "e", "i", "o", "u", but you are not checking for "A", "E", "I", "O", "U".
As a consequence, you get "Test 1 guessed a consonant" when the input was "E".
If you want the comparison to be case sensitive, you should add the uppercase letters to your check. If you don't care about case sensitivity, you can apply the function toLowerCase() to your variable playerGuess before comparing it.
