    Function trimEndDotSlashes

    • trim all trivial trailing forward-slashes ("/") and dot-slashes ("./"), at the end a string. but exclude non-trivial dotdotslash ("/../") from being wrongfully trimmed.

      TODO: this operation is somewhat expensive, because:

      • the implementation uses regex, however it was not possible for me to design a regex that handles the input string as is, so I resort to reversing the input string, and using a slightly easier-to-design regex that discovers trivial (dot)slashes in reverse order, and then after the string replacement, I reverse it again and return it as the output.

      Parameters

      • str: string

      Returns string
