Svelte component runs everywhere, adapter for react/vue2/vue3/svelte.
Managing support for libraries that provide UI components across frameworks can be challenging, especially when Web Components are not an option (e.g. for server-side rendering or best performance). However, the Svelte framework provides a good backward compatibility solution for making Svelte components run in old React or Vue projects. This is especially useful when a team's technology stack is not unified, as it enables cross-framework sharing of components.
Svelte is a framework that provides a solution for managing support for UI components across different frameworks. It offers adapters for React, Vue2, and Vue3, allowing Svelte components to run in projects built with these frameworks. The Svelte CLI simplifies the process of creating components that can be shared across different frameworks. By using Svelte, developers can improve efficiency, achieve cross-stack reuse of components, and ensure visual unity across different technology stacks.

React is a widely used JavaScript library for building user interfaces and single-page applications. It follows a component-based architecture and uses a virtual DOM to efficiently update and render UI components
Vue.js is a lightweight and flexible JavaScript framework that allows developers to easily build dynamic and reactive user interfaces. Its intuitive syntax, modular architecture, and focus on performance make it a popular choice for modern web development.
