Svelte provides a different approach to building web apps than some of the other frameworks covered in this module. While frameworks like React and Vue do the bulk of their work in the user's browser while the app is running, Svelte shifts that work into a compile step that happens only when you build your app, producing highly-optimized vanilla JavaScript.

The outcome of this approach is not only smaller application bundles and better performance, but also a developer experience that is more approachable for people that have limited experience of the modern tooling ecosystem.

Svelte sticks closely to the classic web development model of HTML, CSS, and JS, just adding a few extensions to HTML and JavaScript. It arguably has fewer concepts and tools to learn than some of the other framework options.

Its main current disadvantages are that it is a young framework — its ecosystem is therefore more limited in terms of tooling, support, plugins, clear usage patterns, etc. than more mature frameworks, and there are also less job opportunities. But its advantages should be enough to make you interested to explore it.

, one of its most requested features. We'll look at it later on in this tutorial series.

for a really quick introduction to the basic concepts, before returning to this tutorial series to learn how to build something slightly more in-depth. It should take you about 30 minutes to complete.

Svelte can be used to develop small pieces of an interface or whole applications. You can either start from scratch letting Svelte drive your UI or you can incrementally integrate it into an existing application.

Nevertheless, Svelte is particularly appropriate to tackle the following situations:

(a framework based on Svelte), you can also develop applications with advanced features like server-side rendering, code splitting, file-based routing and offline support. And then there's also

, which lets you build native mobile applications.
