Here is a library I created to help with some basic string manipulation.
Added a few basic functions such as capitalize(), capitalizeWords(), capitalizeHeadline(), removeExtraSpaces() (currently not working), kabobCase(), snakeCase(), camelCase(), shift(), makeHashTag(), and isEmpty().
All of these functions manipulate the string in some way related to the function title and all have very simple usage. Hopefully before long I will have them all working and available to download through NPM. I could not get the Github linked to the NPM. Confusing documentation is giving me problems understanding.
