Find the first vowel using regular expressions (Javascript)

Question

I am trying to create a Latin pig converter that breaks a string into the first vowel and switches the first substring to the second (e.g. dog → ogd).

The following regular expression code works for single vowel strings, however, when trying to translate a word with multiple vowels, it breaks the string into the last vowel:

string.replace(/(\w+)([aeiou]\w+)/i, '$2$1')

Running this code in the word "value" results in "ingmean" (splitting on "i"), while I expect to return "eaningm" (splitting on "e")

Thanks!

Answer 1

You need to add a lazy ( ? ) Operator:

 string.replace(/(\w+?)([aeiou]\w+)/i, '$2$1') 

Answer 2

That should do the trick

 /([^aeiou]+)([aeiou])([a-zA-Z]+)/ 

And use

$ 2 $ 3 $ 1
