Can someone explain what is Prolog and how it's used in programming? or What is Prolog, and why is it

Prolog’s syntax is wild, yeah, but it’s because it’s built for logic puzzles.

what is prolog good for? Classic AI stuff, like theorem proving or even game design (e.g., solving Sudoku).

If you’re curious, try the "Learn Prolog Now!" book (free online). It’s old but gold.
