Svelte is a modern JavaScript framework used to build user interfaces. Unlike frameworks like React or Vue, which do most of their work in the browser, Svelte shifts that work into a compile step. This means your code is compiled into highly efficient vanilla JavaScript at build time, resulting in smaller and faster applications.
Key Features
- No virtual DOM – updates are applied directly to the DOM.
- Reactive programming – variables update the UI automatically when they change.
- Smaller bundle size – produces optimized JavaScript without heavy runtime libraries.
- Simplicity – less boilerplate code compared to other frameworks.
When to Use Svelte
- For building fast and lightweight web applications.
- When you want a simpler alternative to React or Vue.
- For projects where bundle size and performance are critical.
- For developers who prefer minimal boilerplate code.
In short, Svelte makes it easier to build reactive, fast, and efficient apps by doing the heavy lifting during compilation rather than at runtime.
