In this project, some string methods are added to the built-in string methods through the String prototype in Javascript. Also include test cases that were perform on these methods.
The String class in Javascript is extend. Using Prototype Oriented Programming, methods, procedures and instance attributes are added to the String class to support more string manipulation features.
-
hasVowels(typeof Boolean): Returns true if the string contains vowels. This method uses Regular Expression. -
toUpper(typeof String): Returns the String in question but with all characters in upper cases as applicable. This method is implemented using Regex. -
toLower(typeof String): Returns the String in question but with all characters in their lower cases as applicable. This method is implemented using Regex. -
ucFirst(typeof String): Returns the String in question but changes the First Character to an Upper case. -
isQuestion(typeof Boolean): Return true if the string is a question (ending with a question mark). This method implements Regular Expression. -
words: Returns a list of the words in the string, as an Array. This method implements Regular Expression. -
wordCount(typeof Number): Returns the number of words in the string. -
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. -
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 implements Regular Expression.
**Note**: This project is completed using ES5
- All the prototyped methods are covered fully with tests
- The tests cover the methods as well as the conditions/procedures that the methods employed
- All the comparators used for the tests are optimized or most efficient comparator for the scenario
