This is a Ruby function
def new_count(word)
word.downcase!
return 1 if word.length <= 3
word.sub!(/(?:[^laeiouy]es|ed|[^laeiouy]e)$/, '')
word.sub!(/^y/, '')
word.scan(/[aeiouy]{1,2}/).size
end
This is an equivalent function in JavaScript.
function newCount(word) {
word = word.toLowerCase();
if (word.length <= 3) return 1;
word = word.replace(/(?:[^laeiouy]es|ed|[^laeiouy]e)$/, '');
word = word.replace(/^y/, '');
return word.match(/[aeiouy]{1,2}/g).length;
}
