If it's hard to understand any code, most probably it's not well-written, thus the inability to read it. The best approach I can suggest would be to read line by line, at the slowest pace possible, until you get what it actually does. Yes, it will become boring and exhausting at first, but eventually you will train your brain to see various patterns and understand idioms and schemas without realizing it. It's like us humans we start with baby steps and eventually we learn how to stand on our feet and run. Now, if you want to master your craft, in this case the aforementioned running, then you will have to specialize through constant training and finding a coach to guide you how to improve your existing experience and what things you should avoid doing, let alone discard bad practices. That's really it, I'm afraid :/
