Overview of this book

Svelte has quickly become a popular choice among developers seeking to build fast, responsive, and efficient web applications that are high-performing, scalable, and visually stunning. This book goes beyond the basics to help you thoroughly explore the core concepts that make Svelte stand out among other frameworks. You’ll begin by gaining a clear understanding of lifecycle functions, reusable hooks, and various styling options such as Tailwind CSS and CSS variables. Next, you’ll find out how to effectively manage the state, props, and bindings and explore component patterns for better organization. You’ll also discover how to create patterns using actions, demonstrate custom events, integrate vanilla JS UI libraries, and progressively enhance UI elements. As you advance, you’ll delve into state management with context and stores, implement custom stores, handle complex data, and manage states effectively, along with creating renderless components for specialized functionalities and learning animations with tweened and spring stores. The concluding chapters will help you focus on enhancing UI elements with transitions while covering accessibility considerations. By the end of this book, you’ll be equipped to unlock Svelte's full potential, build exceptional web applications, and deliver performant, responsive, and inclusive user experiences.

The onChange prop, on the other hand, is used to pass in an event handler that will be called when the value changes from within the calendar component. We saw how we could handle event handlers in a UI library in the previous section when we discussed CodeMirror.

So, here is what I think using the calendar action would look like:

<div
  use:calendar={selectedDate}
  on:change={(event) => selectedDate = event.detail}
/>

Here, event.detail is the data attached to the...
