Svelte 3: What You Need to Know About Svelte v. 3
Introducing Svelte 3, the innovative component framework for building web applications! Much like React or Vue.js, Svelte is a tool for developers to construct robust web applications. However, Svelte 3 distinguishes itself through a unique approach.
In May 2023 realised version 3.58.0
Unlike traditional frameworks, Svelte 3 operates at build time. This means it takes your components and converts them into highly efficient imperative code that updates the Document Object Model (DOM) directly. This results in a decrease in browser workload as it eliminates the need for time-consuming operations like virtual DOM diffing, leading to excellent performance and smoother user experiences.
Svelte 3 is the outcome of a significant overhaul from its predecessor, Svelte 2. The Svelte team spent 12 months focusing on creating an outstanding developer experience. As a result, Svelte 3 enables you to write components with significantly less boilerplate than you’ll find in many other frameworks.
Svelte 3 represents the future of web development, offering you the chance to write ambitious applications with optimal performance characteristics. Try it out today, and join the next generation of web app development!
