Question

In AppleScript it’s possible to get the the POSIX path of the folder the current script is located in using this line:

POSIX path of ((path to me as text) & "::")

Example result: /Users/aaron/Git/test/

What’s the JavaScript equivalent?

Answer 1

Pure JXA code without ObjC involved:

App = Application.currentApplication()
App.includeStandardAdditions = true
SystemEvents = Application('System Events')

var pathToMe = App.pathTo(this)
var containerPOSIXPath = SystemEvents.files[pathToMe.toString()].container().posixPath()
