Svelte

Svelte is a free and open-source front end compiler[4] created by Rich Harris and maintained by the Svelte core team members.

Svelte applications do not include a framework script. Instead, building a Svelte application generates the necessary code to manipulate the DOM within each component, which may reduce the size of transferred files as well as give better client startup and run-time performance. Svelte has its own compiler for converting app code into client-side JavaScript at build time. It is written in TypeScript.[6][7] Unlike the traditional frameworks (React and Vue) which carry out the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when an app is built.[8] The Svelte source code is licensed under MIT License and hosted on GitHub.
