Welcome to Svelte and Sapper in Action! We’ll start here by learning why these approaches to web development deserve your attention, then we’ll learn about Svelte Native, compare Svelte to other popular web frameworks, and delve into the tools you’ll need to get started. We’re also going to build our first Svelte application with an online tool called the REPL. Apps built this way can be saved, shared with others, and exported to continue development locally.
