Modern front-end frameworks claim to be reactive when state changes occur which updates the views at runtime. The technologies these frameworks depend on to do so aren't the most optimal such as using the Virtual DOM, DOM diffing, and more. Svelte is a compiler that runs at build time instead to optimize what state changes are possible in your app so that it can be more light-weight and respond faster as state changes occur. In this talk, we'll explore the basics of Svelte and what makes it different from frameworks like React and Vue.js that dominate the market.
