What is Svelte? Nedir?
Svelte is a compile-time frontend framework that doesn't use a virtual DOM and delivers extremely high performance.
Svelte was developed by Rich Harris in 2016. Unlike other frameworks, Svelte works at compile time rather than runtime. This approach eliminates the need for a virtual DOM and produces very small, high-performance applications. Svelte's syntax is extremely simple and intuitive. Reactivity is achieved directly through variable assignments; there's no need to learn special APIs or hooks. .svelte files naturally combine HTML, CSS, and JavaScript. CSS scoping is done automatically. Svelte offers simple and effective state management with its Store system. Transition effects and animations are built into the framework. SvelteKit (Svelte's meta-framework) provides full-stack features like SSR, static site generation, file-based routing, and form handling. Consistently ranked among the most loved frameworks in Stack Overflow and State of JS surveys, Svelte is used by Apple, Spotify, The New York Times, and Square.
