Tell us what’s happening:

why am I getting this error :sweat_smile:
TypeError: unknown: (0 , s.extname) is not a function

Your code so far


import { uppercaseString, lowercaseString } from './string_functions.js';
// add code above this line

uppercaseString("hello");
lowercaseString("WORLD!");

There is an issue on the github looking into this. So, it is not you but the challenge is broken. For now, just understand what this lesson is teaching, back out of it, and try to move onto the next challenge. You can come back and do this one later. Or not.

My code is working fine and completing all the test cases, it’s just that it’s giving me a warning/error “ReferenceError: require is not defined”. I don’t get it why?
