Introduction

Svelte is a modern JavaScript framework that shifts the work from the browser to the compile step, making your applications faster and more efficient.

Key Features

• No Virtual DOM: Unlike React or Vue, Svelte compiles your code to tiny, framework-less vanilla JavaScript.
• Reactive Assignments: Directly update variables and the DOM updates automatically.
• Built-in Optimizations: Automatically optimizes code during the compile step.

Comparison with Other Frameworks

React

• Virtual DOM: React uses a virtual DOM to optimize updates.
• JSX: Uses JSX syntax which combines HTML and JavaScript.
• Component-based: Emphasizes a component-based architecture.

Vue

• Reactivity: Similar reactivity system but uses a virtual DOM.
• Single File Components: Encapsulates HTML, JavaScript, and CSS in one file.
• Community: Strong community support and extensive ecosystem.

Conclusion

Svelte offers a unique approach by shifting the work to the compile step, resulting in faster and more efficient applications.
