Problem Many component libraries, especially those built with vanilla Web Components, follow a specific way of dealing with boolean attributes, specified by the HTML Living Standard.

Problem Building a Lit Element component, and defining their properties for internal consumption is very well explained.

Introduction In this article we aim to develop a fundamental understanding of what Web Components are, by methodically and comprehensively building and modifying our own standalone Web Component through a variety of patterns.
