`<=': comparison of Fixnum with Array failed (ArgumentError)

Question

In this code I am trying to remove the last vowel in the word. Once I ran the code, I received an argument error stating "comparison of Fixnum with Array failed(ArgumentError). Please help!

VOWELS = %w( a e i o u)

def hipsterfy(string)

  new_string = string.split('')

  reversed_string = new_string.reverse

  i = 0

  while i <= reversed_string

     if VOWELS.include?[i]

        reversed_string[i] = ('')

    i += 1
    end
    reversed_string
  end

  reversed_string.reverse 

end

Hint: If you run out of vowels does `i` get incremented? You also need to dig into regular expressions or, at the very least, the [`tr`](https://ruby-doc.org/core-2.2.0/String.html#method-i-tr) method. — tadman, Sep 22 '16 at 18:19

I am sure this is not the only glith with this code, but the error you got came from here:

while i <= reversed_string

it probably should be

while i < reversed_string.length

since reversed_array is an array, and you probably want to compare i against it’s length.

When you test

if VOWELS.include?[i]

you're checking if the VOWELS constant includes the array index. You want to look at the letter at that point in the string instead, right?

if VOWELS.include?(reversed_string[i])

There needed to be a "break" statement after the if statement to stop the loop as soon as it looped the first vowel. That would prevent it from going on to the next vowel. PROBLEM SOLVED.
