Svelte Training Overview
Svelte is a JavaScript library for building user interfaces, but instead of running in the browser (like React and Vue), Svelte runs at build time, surgically updating the DOM. As a result, developers are able to write higher-performance applications that run faster and more efficiently.
Accelebrate's live, private Introduction to Svelte training course teaches attendees the basics of Svelte and then dives in deeper with templates, components, state, actions, and more.
