You changed the name of the original function in 'fizzbuzz.js'\n2. Something might've messed up the original module.exports line at the bottom of the 'fizzbuzz.js' file\n3. Something messed up the 'require' line in the 'fizzbuzz.test.js' file\n4. The 'fizzbuzz.js' file you're working in could be in the wrong directory\n\nWhat do you do if you can't get it to work? I'd say copy the 'fizzbuzz.js' and 'fizzbuzz.test.js' files and delete the one's that aren't working. You can keep your code of course, just paste it into the fresh files and test away! If you really can't get it to work, contact [email protected]!`)
