Svelte JavaScript Framework

Svelte is a modern JavaScript framework for building user interfaces. Unlike traditional frameworks such as React and Vue, Svelte shifts the work from the browser to a compile step in your development process.

Write Less, Do More

Svelte keeps the reactivity inside the component logic by using a readable store. By keeping the reactivity inside the logic of the component, Svelte ensures better performance and a simpler programming model.

Reactive Declarations

Svelte has a unique feature called reactive declarations. It allows you to declare variables that automatically update when the state changes.


Like other frameworks, Svelte uses props to pass data down from parent components to child components.

LifeCycle Functions

Svelte provides lifecycle hooks similar to those in class-based components of React.
