Is it possible to have 2 different game versions on the same computer?

I want to try out the new unstable 1.19 updates, but if I do that I loose my current version for my world.  Is it possible to download 1.19 and still keep my 1.18 version?  If I downloaded it to a different folder or something.  I'm not much of a computer person so please explain how to do it, if if is possible.
