Prolog is like programming with logic instead of explicit instructions. Rather than telling the computer how to do something, you state what is true and let it figure out the solution. It's like having a clever assistant that draws conclusions for you-ideal for AI, expert systems and puzzle solving.
The language is known for its powerful handling of rules, patterns and backtracking. It is often used in research, but also in practical applications such as natural language processing and scheduling. With implementations like SWI-Prolog and Tau Prolog there are plenty of tools for both beginners and professionals.
If you enjoy thinking in terms of rules and relationships instead of step-by-step instructions, Prolog can open up a whole new world of programming.
