fizzBuzz exercise

hi guys, i couldn’t get the node js going so i am working on webstorm

anyway, my prblem is that i am copying those 3 lines of code as in the exercise but instead of getting the ‘Buzz’ outcome i get undefined.

Can anyone help me to define the problem, this js just doesn’t work for me and i am trying to grasp in in 5 weeks without a success :(((

can you capture a photo and send it ?
