Great explanation of HTML entities, especially the example of displaying reserved characters like < and > without having them interpreted as HTML. For developers who don't need to memorize all the entity references, an HTML encoder can be really useful when working with dynamic text or code snippets. I also find an HTML encoding tool handy when I need to encode HTML online quickly instead of manually replacing characters. This https://www.utilityforweb.com/html-encode/ is useful for those quick conversions.
