title: Can't import class in Javascript
body: <p>I simply can't seem to import classes in Javascript anymore. </p>
  
  <p>My App.js: 
  <a href="https://i.stack.imgur.com/bUKb5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bUKb5.png" alt="enter image description here"></a></p>
  
  <p>My User.js (None of the classes import, but the statement to import this class comes first as you will see in the error) :
  <a href="https://i.stack.imgur.com/Vs4nK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Vs4nK.png" alt="enter image description here"></a></p>
  
  <p>The error message:
  <a href="https://i.stack.imgur.com/A0dzD.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/A0dzD.png" alt="enter image description here"></a></p>
  
  <p>I know that:
   - the paths to the classes are right
   - the names of the classes are right and that the IDE recognizes them (the IDE suggests what values need 
     to be in the constructor)
   - This way of importing / exporting the class should be right </p>
