Fundamentals of 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 can write higher-performance applications that run faster and more efficiently.
This Svelte course teaches attendees the fundamentals of this innovative JavaScript framework. Attendees learn how to set up a development environment and implement the core features of SvelteKit, including routing, server-side rendering, and unit testing. Participants create static and dynamic pages, understand template reactivity, and work with Svelte components. The course covers event handling, forms, lifecycle, state management, and routing. Attendees also explore advanced topics, including error handling and asynchronous data. By the end of this course, participants will confidently build robust, high-performance web applications with Svelte.
