Nice challenge! Validating a Sudoku board really sharpens logic skills—especially when working with sets and nested loops in JavaScript.
I’ve been doing little side projects to keep things fun. Recently played around with a Stylish Fonts Generator while building a custom UI—it’s a neat tool for adding some flair to headers or user-generated content fields. Simple, but cool if you're into front-end experiments.
Looking forward to more of these JS puzzles!
