What is reactivity in Svelte?

What is reactivity in Svelte?

Reactivity in Svelte refers to how the framework automatically updates the DOM when the state of your application changes.

Can you give me an example of how reactivity works in Svelte?

Sure! In Svelte, you can create a reactive variable using the $: syntax. For example, if you have a variable count, you can write $: doubled = count * 2; and doubled will automatically update whenever count changes.

What are some benefits of using reactivity in Svelte?

Some benefits include improved performance, less boilerplate code, and a more intuitive way to manage state changes.

How does Svelte's reactivity differ from React's?

Svelte compiles your components into highly efficient imperative code at build time, while React uses a virtual DOM to manage updates at runtime.
