Haskell is most likely quite different from any language you've ever used before. Compared to the usual set of concepts in a programmer's mental toolbox, functional programming offers us a profoundly different way to think about software. In Haskell, we de-emphasise code that modifies data.
On the back-end, you can use many languages, including Java, PHP, C#, and (only since a few years) JavaScript with NodeJS. The main adavantages of using JavaScript with NodeJS on the back-end are: Since you anyway need to be good at JavaScript programming for doing your job on the front-end, if you are also using it on the back-end, you only have to master a single language (and its tooling), instead of two. That's a huge benefit.
