Is it better to start from scratch rather than refactoring? (lemmy.sdf.org)

Refactoring gets really bad reviews, but from where I'm sitting as a hobby programmer in relative ignorance it seems like it should be easier, because you could potentially reuse a lot of code. Can someone break it down for me?

I'm thinking of a situation where the code is ugly but still legible here. I completely understand that actual reverse engineering is harder than coding on a blank slate.

My current team has had a great solution to this, which is to re-build in parallel. Build the new system alongside the old one, including the reporting and integrations. You'll find the edge cases pretty quickly.

So how is that different from refactoring?
