Welcome to the iwantcoding.com Svelte Tutorial. Svelte is a compile-time framework: there's no virtual DOM at runtime — your .svelte files are compiled into small, surgically efficient JavaScript that updates the DOM directly.

What this tutorial covers

ChapterYou will learn
Svelte BasicsComponents, props, runes ($state / $derived / $effect), events, bindings.
Logic & Control Flow{#if}, {#each}, {#await}, {#key}, and the new {#snippet} blocks.
Lifecycle & ModulesonMount, context, stores, actions, transitions, motion springs.
SvelteKitFile-based routing, load() functions, form actions, hooks, deploys.
ExamplesRunnable snippets, quiz, exercises, bootcamp, certificate.

Who this is for

  • Anyone who finds React noisy — less ceremony, less re-render thinking.
  • Performance-budget apps — tiny runtime, great Lighthouse scores by default.
  • SvelteKit-curious devs — a full-stack framework with the same compile-time magic.
How to use this tutorial: read the chapter, run the example with Try it Yourself », do the exercise, then take the quiz at the bottom. Hit Mark complete when you're done — the sidebar will track your progress.
