CoffeeScript function: Counts the number of vowels within a string
CoffeeScript Function : Exercise-14 with Solution
Write a CoffeeScript function that accepts a string as a parameter and counts the number of vowels within the string.
Note : As the letter 'y' can be regarded as both a vowel and a consonant, we do not count 'y' as a vowel here.
Example string : 'The quick brown fox'
Expected Output : 5
HTML Code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="//jashkenas.github.io/coffee-script/extras/coffee-script.js"></script>
<title>Counts the number of vowels within a string
</title>
</head>
<body>
</body>
</html>
CoffeeScript Code:
vowel_count = (str1) ->
vowel_list = 'aeiouAEIOU'
vcount = 0
x = 0
while x < str1.length
if vowel_list.indexOf(str1[x]) != -1
vcount += 1
x++
vcount
console.log vowel_count('The quick brown fox')
Sample Output:
5
