Other solution instead of redirect also possible?

This seems to be a shorter solution instead of doing a redirect. Does it have any downsides?

const side = req.query.side || "question";

Hi Oliver,

It depends on what your app does, and what you think you might want it to do in the future. Either way is acceptable but the redirection approach will afford you greater flexibility. The concept you want to keep in mind when making decisions like this goes by the name of the Single-Responsibility Principle. Basically, you want each function you write to have only one reason to change, ever; the last thing you want is for one of your routes to be handling 17 different conditions of your app.

Hmmm... I have learned of the DRY principle from Treehouse, but I have never heard of the Single-Responsibility Principle. Not sure why this is the first time I'm hearing of this. It's important to learn good programming habits from the start as that can save a lot of trouble and headache down the road.

the solution seems ok, but if you input 'hint' as value for the 'side' it would be accepted and the side value in the query won't be changed to 'question' if that is what you intended to do.
