Svelte is an innovative component framework that compiles code to highly efficient vanilla JavaScript at build time. Unlike traditional frameworks that do most of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app.

The source code for Svelte is available on GitHub, providing a platform for developers to contribute, report issues, and explore the code: s://github.com/sveltejs/svelte(https://github.com/sveltejs/svelte).

Svelte's documentation is comprehensive and includes tutorials, API documentation, examples, and more, making it an invaluable resource for developers: s://svelte.dev/docs(https://svelte.dev/docs).

The official website for Svelte not only offers documentation but also showcases examples, community resources, and the latest news about the framework: s://svelte.dev/(https://svelte.dev/).

Svelte's main features include its unique compile-time approach to building user interfaces, resulting in smaller bundle sizes, faster runtime performance, and an intuitive API that enhances developer productivity.

```svelte <script>

 let name = 'world';

</script>

<h1>Hello {name}!</h1> ```

```svelte <script>

 let count = 0;

 function handleClick() {
   count += 1;
 }

</script>

<button on:click={handleClick}>

 Clicked {count} {count === 1 ? 'time' : 'times'}

</button> ```

```svelte <script>

 export let name;

</script>

<h1>Hello {name}!</h1> ```

```svelte <script>

 let loggedIn = true;

</script>

{#if loggedIn}

 
You are logged in

{:else}

 
You are not logged in

{/if} ```

```svelte <script>

 let cats = ['Whiskers', 'Bob', 'Tom'];

</script>

<ul>

 {#each cats as cat}
   
{cat}
 {/each}

</ul> ```

```svelte <script>

 let promise = fetch('https://api.example.com/user');

</script>

{#await promise}

 
Loading...

{:then user}

 
Hello {user.name}!

{:catch error}

 
Error: {error.message}

{/await} ```

```svelte <script>

 let name = '';

</script>

<input bind:value={name} placeholder=“Enter your name”> <p>Hello {name}!</p> ```

```svelte <script>

 import { onMount } from 'svelte';

 onMount(() => {
   console.log('Component mounted');
 });

</script> ```

Svelte's innovative approach sets it apart, but it faces competition from other modern frameworks: 1. **React**: A declarative, component-based JavaScript library for building user interfaces. 2. **Vue**: A progressive framework for building user interfaces. 3. **Angular**: A platform and framework for building client-side applications. 4. Ember: A framework for ambitious web developers. 5. Preact: A fast 3kB alternative to React with the same modern API.

This structured summary provides an overview of Svelte, highlighting its innovative approach to web development, how to get started with coding in Svelte, and its position in the competitive landscape of web frameworks. For developers looking to build fast, reactive web applications, Svelte offers a compelling option with its unique compile-time framework.
