Why Svelte?

To understand what's special about Svelte, we need to look at how it differs from other popular libraries and frameworks, such as Angular, React, and Vue.

Svelte versus the other frameworks

Svelte's goal is to help developers write less code, letting them build components using familiar HTML, CSS, and JavaScript. Just like React ones, Svelte apps are truly reactive, so you do not need to manipulate the DOM directly (as you would if you were using jQuery, for example): the view is automatically updated on every change in the state.

However, Svelte's main intuition, and its biggest difference from all the other popular JavaScript frameworks, is that it moves most of the processing to a compilation stage. That is, rather than relying on large and complex libraries loaded at run time, Svelte is built around a compiler that processes your application's code before emitting a small, fast, and optimized code bundle.
