Why? Even at the level of Advanced Beginner (which is pretty concrete and easily attainable), FP is already hugely useful. Everything at that level is both useful and relatively easy to understand. It's going to improve your code even if you use a language not particularly tailored for FP.

The rest is just icing on the cake, and you don't have to deal with it if you don't find it interesting.

Comments like this are more likely to do that than the original post. Just give it a bash and someone will help you if you struggle, I would.
