In NodeJS/ExpressJS, how should one decide between using request params and query strings?

While I am starting to get a hold of NodeJS programming, I am a bit confused by when to use request params and how their practical use differs from using query strings.

In particular, I can do localhost:8080/:param1 in the URL followed by req.params in the code or localhost:8080/?param1=value in the URL followed by req.query in the code, and get the same outcome – the value of param1. How should I decide when to use which? What is a good use case for either of these approaches?
