body: <p>Im currently doing TylerMcginnes React Fundamentals course , while I am relatively new to front end I wish to learn to the current accepted style so am linting with eslint airbnb config and prettier, however since i changed from Tyler's coding a.k.a(no imports, all requires, no es6 functionality) i have got this "Field "browser" doesnt contain a valid alias configuration error and it says that my index.jsx doesnt exist in the exact location that it is?? </p>

  <p>I have looked at every other answer regarding this issue and most seem to be typo's, it would drive me crazy if I'm so blind i couldn't see it after the time I've spent looking</p>
