An exciting game of programming and Artificial Intelligence*

In WarriorJS, you wear the skin of a warrior climbing a tall tower to reach The JavaScript Sword at the top level. Legend has it that the sword bearer becomes enlightened in the JavaScript language, but be warned: the journey will not be easy. On each floor, you need to write JavaScript to instruct the warrior to battle enemies, rescue captives, and reach the stairs alive...

No matter if you are new to programming or a JavaScript guru, WarriorJS will put your skills to the test. Will you dare?

Quick Start

  1. Install WarriorJS with npm:
npm install --global @warriorjs/cli

Good luck in your journey, warrior!
