functions like: truncate string if longer than 30 characters, retu

Answer 1

Helper is collection of user-defined or pre-defined functions, no need to instantiate as well as libraries are classes needs to instantiate to use them. Library might contain user-defined and pre-defined functions/methods too. Function defined in library (class) is known as method!
