Coding Challenge#5: Are we Alternate? (Code included)

Question

Are we alternate? (By: Jafca)
Create a function isAlt() to validate whether a string of letters has alternate consonants and vowels. Vowels are a, e, i, o and u.
e.g. isAlt("amazon")
// true
e.g. isAlt("cheeze")
// false
e.g. isAlt("banana")
// true
e.g. isAlt("ghost")
// false

A solution constructing a RegEx, should also work for any other set of non-meta characters:

Answer 4

@Tamas. Actually. Me too. For the original question by Jafca, I did not check explicitly for one letter inputs. Maybe I should have specified it in the question

Answer 8

@pixie i have made the changes please have a look

Answer 9

what about single consonant char? should they also be true??

Answer 10

@pixie should 'b' also be true?
or rule is only for vowels?

Answer 11

@Riman. Only for vowels

Answer 12

@Tamas. The output for 'b' should be false as there are no vowels in the input.

Answer 13

Me too, then. Maybe you should add the requirement that the word must contain a vowel in the description, as this is logically independent of the alternating rule.

Answer 18

@pixie i can't understand why?

Answer 19

@pixie there is not any consonant in a single letter 'a' so it is not alternate

Answer 20

@Pixie: then I misunderstood the problem
