<p>Are our UI tests a chore, or do they help us move faster? Let’s examine what makes testing great and not so great. We’ll focus on test strategies that help us code with confidence and clarity, and where they can cost us time and energy. The secret to good testing lies in how it shapes our developer experience. Do our tests give us useful feedback in a timely manner? How quickly can we tell what is wrong when a test suite fails? Do they document our features and explain our past decisions? We’ll answer these questions with better tests that give us joy.</p>

Testing Our Way to a Better Developer Experience

<p>Your first JavaScript tool might not be the next Babel or ESLint, but it can be built on them! Let's demystify the secret art of JavaScript tools, how they work, and how to build our own. We'll discover the opportunities in our everyday work to apply these techniques, writing our own ESLint rules to prevent mistakes and code transforms to make breaking changes easy to apply. We’ll walk through the fundamentals of working with an abstract syntax tree, and develop our understanding through a live-code. You will be amazed at what you can build, and together we’ll explore how to get started.</p>

Web components are a set of web platform APIs that allow developers to create custom, reusable HTML tags to use in web pages and web apps. They are made up of four main technologies: HTML templates, custom elements, Shadow DOM, and HTML imports. HTML templates allow developers to declare inert chunks of HTML that can be used as the foundation for an element's structure. Custom elements enable developers to define their own HTML tags and extend existing ones. Shadow DOM provides encapsulation for styling and DOM manipulation. Finally, HTML imports allow developers to include and reuse HTML documents in other HTML documents.
