Coding Dojo is a practice of pair programming and test-driven development (TDD) where pairs of programmers take turns solving coding problems for short periods, explaining their work, and receiving feedback from others. The goal is to improve skills through collaboration and focusing on writing automated tests before code ("red => green => refactor"). Programmers rotate frequently to work with different partners on challenges in languages like Ruby.
