Svelte vs React

Svelte and React are two popular JavaScript frameworks for building web applications. Svelte is a relatively new, modern and lightweight framework that has gained a lot of popularity recently, while React is a well-established and widely used framework known for its robustness and flexibility.

Svelte is a component-based framework that focuses on compile-time optimizations. It compiles your code into highly efficient JavaScript code that is optimized for performance. Unlike React, Svelte is a compiler-driven framework, which means it does most of the work at build time. This results in very fast and lightweight applications as it does not require a lot of overhead to run.

On the other hand, React is a virtual DOM-based framework that facilitates the development of large-scale applications by managing the state and rendering of UI components. React uses a component-based architecture, allowing developers to build reusable UI components that can be easily integrated into more complex applications. React is known for its flexibility, high performance, and strong developer community.

In summary, while both frameworks are used for building web applications, Svelte takes a different approach to optimize the performance of web applications which can result in faster and lighter code. React, on the other hand, is a more established framework that offers a robust and flexible component-based architecture for building complex web applications.
