The available methods of this Class are listed below:
-

toUpper (typeof String): Returns the String in question but with all characters in upper cases as applicable. This method should be implemented without the use of the toUpperCase internal methods. -
toLower (typeof String): Returns the String in question but with all characters in their lower cases as applicable. This method should be implemented without the use of the toLowerCase internal methods. -

wordCount (typeof Number): Returns the number of words in the string. It must make use of the words method above. -
toCurrency (typeof String): Returns a currency representation of the String e.g 11111.11 should be represented as 11,111.11. -
fromCurrency (typeof Number): Returns a number representation of the Currency String e.g 11,111.11 should return 11111.11 -
inverseCase (typeof String): Returns each letter in the string as an inverse of its current case e.g Mr. Ben should return mR. bEN. -
alternatingCase (typeof String): Returns the letters in alternating cases. It must start with a lower case e.g Onomatopoeia should return oNoMaToPoEiA. -
getMiddle (typeof String): Returns the character(s) in the middle of the string e.g read should return ea and reads should return a. -
numberWords (typeof String): Returns the numbers in words e.g 325 should return three two five. -
isDigit (typeof Boolean): Returns true if the string is a digit(one number) e.g 3 should return true and 34 should return false. This method must implement Regular Expression. -
doubleCheck (typeof Boolean): Returns true if a string contains double characters(including whitespace character) e.g aa, !!, should return true.
The limitations of this class is that it is not a standalone class but built on the String.prototype
of the string class
