Svelte is a modern JavaScript framework
Yes, Svelte is indeed a modern JavaScript framework, but it works a bit differently from other frameworks like React, Angular, or Vue. Rather than using a virtual DOM and running client-side JavaScript to update the UI in response to state changes, Svelte compiles your components into efficient imperative code at build time. This results in smaller bundle sizes and faster runtime performance.
Here are some key features and benefits of Svelte:
-
No Virtual DOM: Unlike React and similar frameworks that rely on a virtual DOM to update the UI, Svelte directly updates the DOM when the state changes, which makes it more efficient and faster.
-
Compiles to Vanilla JavaScript: Svelte components are written in a declarative syntax with HTML, CSS, and JavaScript, but during build time, Svelte compiles them into optimized vanilla JavaScript, which eliminates the need for a framework to be loaded in the browser at runtime.
-
Smaller Bundle Sizes: Since Svelte compiles away the framework code, the resulting application tends to have smaller file sizes, leading to faster load times.
-
Reactivity: Svelte uses a unique approach to reactivity, where you can simply assign a value to a variable, and the framework automatically tracks and updates the DOM when that value changes. There is no need to call
setStateor similar methods. -
Simplicity: The syntax in Svelte is straightforward and easy to understand, which makes it a great option for developers looking to quickly build interactive applications without a steep learning curve.
-
Built-in Features: Svelte provides built-in features like animations, stores for state management, and scoped CSS without needing external libraries.
-
SvelteKit: This is the official framework for building full-stack applications with Svelte. It provides routing, data loading, and server-side rendering out of the box.
