This implementation extends the functionality of the String class by adding more utility methods.

The tests are run using jasmine on the command line

To run the tests, use the following steps:

• Clone the repo locally and navigate to the newly created folder

  $ git clone [email protected]:andela-ekupara/StringClass.git $ cd StringClass

• Open the index.html file in your browser to see the tests run.

• words()
• wordCount()
• toCurrency()
• fromCurrency

1. Method hasVowels()
