Damn, it feels good to be back! If you’re reading this, you probably don’t know much about Protocols or Records and the goal is simple – by the end of this post, you’ll feel comfortable understanding them, using them, and refactoring to them if you’re coming from a Java codebase.</p> <h4 id="protocols">Protocols</h4> <p>If you haven’t read the post <a href="http://www.bradcypert.com/mighty-morphing-multimethods/" target="_blank" rel="noopener">on multimethods yet</a> , go ahead. I’ll wait. Protocols are conceptually similar to multimethods, although protocols dispatch on the type of parameter, while multimethods dispatch on the value. Although, technically, you can dispatch on a multimethod on type but it’s not a good practice.</p>
