In plain words
Prolog.js is a Prolog compiler and interpreter built entirely in JavaScript. It allows users to run Prolog code directly in a web browser without additional installations. The tool includes example programs such as Einstein's Puzzle and list processing exercises, making it useful for learning logic programming or solving constraint problems. It runs entirely in the browser, eliminating setup requirements.
