* CODERBYTE BEGINNER CHALLENGE *

* *

* Vowel Count *

* Using the JavaScript language, have the function VowelCount(str) take the str *

* string parameter being passed and return the number of vowels the string contains *

* (ie. "All cows eat grass" would return 5). Do not count y as a vowel for this *

* challenge. *

* *

* SOLUTION *

* I will be using two for loops that will be nested. I will be searching thru all *

* entries in my vowel array in the outter loop and searching through each letter *

* in the string in the inner loop. I will be comparing each vowel to every letter *

* in the string. If it matches then I will be incrememting by total by 1.

* *

* Steps for solution *

* 1) create my vowel arrray. *

* 2) Initialize tot to zero. *

* 3) Loop through each vowel and compare to each letter in string *

* 4) If match then increment tot by 1 *

* 5) Return tot as answer *

* *
