forEach method vs for loop - return doesn't break from the function

This is more of a help to others than a question. I created very similar code to the given solution but I try and use forEach on arrays where possible. In this setup, I found out that while my code works for the two sets of grades given, if I add an invalid grade the return statement "can't complete calculation" doesn't break from the function.

With some research I found that forEach can't break from the array and will continue through all the elements. https://medium.com/@virtual_khan/javascript-foreach-a-return-will-not-exit-the-calling-function-cfbc6fa7b199
