Svelte is a modern JavaScript framework designed for building user interfaces with a focus on performance and simplicity. Unlike traditional frameworks like React or Vue, Svelte shifts much of the work typically done in the browser to the build time by compiling components into highly optimized, imperative JavaScript. This approach leads to smaller bundle sizes and faster runtime performance. In Svelte, components are written in a simple, HTML-like syntax, with embedded JavaScript and CSS, allowing for a more intuitive and less boilerplate-heavy development experience. For application developers, Svelte offers a reactive programming paradigm where component reactivity is managed automatically, resulting in more maintainable code. Its lightweight ecosystem makes it an attractive choice for both small projects and large-scale applications, especially when client-side performance and ease of use are priorities.
