Svelte is a component framework which runs at build time, converting your components into highly efficient imperative code that surgically updates the DOM. As a result, you can write ambitious applications with excellent performance characteristics.
Svelte has its own compiler for converting app code into client-side JavaScript at build time. The code in Svelte files are converted from an easier-to-write hybrid language that mixes HTML, JavaScript, and CSS into lower-level optimized JavaScript, HTML, and CSS files. All the code is compiled ahead of time, there is no virtual DOM1, and CSS scoping is included.
This is free and open source software.

1 The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree.
