How can I get the last element of a string array with one line of code?

Question

Right now, I get the last part of an URL to exclude the filename like this:

attachmentFileName = attachmentLink.split("/");
attachmentFileName = attachmentFileName[attachmentFileName.length-1];

it feels, as if I could do that in one statement only, but I can't figure out how. Not a big deal, but i think it can be done more elegantly.

attachmentFileName = attachmentLink.split("/")[attachmentFileName.length-1]; Mind. Blown. — Glubus

Are you on on NodeJS? Node has utilities for handling paths and URLs which are more robust than splitting on the slash. — Madara's Ghost

You can use Array.prototype.pop() method to retrieve last element of your splitted array:

attachmentFileName = attachmentLink.split("/").pop();

Please give a try to below code

attachmentFileName = attachmentLink.substring(attachmentLink.lastIndexOf("/")+1,attachmentLink.length);
