Javascript file's parent folder

Question

every time I need to get the name of a folder a file targetFile is located in, I always have to write out this tedious:

var parentFolder = targetFile.path.toString().substring(targetFile.path.toString().lastIndexOf('/'), targetFile.path.toString().length)

am I missing something horribly easy to get this?

Answer 1

Is this something that you need to do dynamically? Why not just store it as a constant?

Alternatively, just create a function that executes the code you pasted...
