The course has been reinforcing the idea that Ruby has multiple ways to do something, but I just don’t see why you would have two methods to do the exact same thing.

Is there a subtle difference or are they identical? (In the case that they are identical, intern uses 6 keystrokes and to_sym uses 7, so I’d imagine that intern would be slightly more useful for the programmer.)

In the exercise, when I replace .to_sym by .intern, it raises an exception, so I guess it’s not exactly the same.
I think in advanced scenarios, there must be differences in how they behave in details.
