🧡 Introduction to Svelte

Svelte is a modern front-end JavaScript framework for building fast and reactive user interfaces. Unlike traditional frameworks like React or Angular, Svelte shifts much of the work to compile time,resulting in highly optimized, minimal JavaScript bundles.

Created by Rich Harris, Svelte was first released in 2016, and it has since gained popularity for its simplicity, speed, and developer-friendly approach.

⚡ Key Features of Svelte​

  • No Virtual DOM: Svelte compiles your code into efficient, imperative JavaScript that updates the DOM directly.
  • Reactive Variables: State management is simple—just reassign a variable, and the UI updates automatically.
  • Built-in Animation & Transitions: Svelte includes tools for adding smooth animations and transitions without extra libraries.
  • Small Bundle Sizes: Since the framework compiles away, the resulting apps are smaller and faster.
  • Component-Based Structure: Like React and Vue, Svelte uses components to structure UI, but with simpler syntax.

🚀 Why Use Svelte?​

  • Cleaner, more readable code
  • Faster performance due to compile-time optimization
  • Minimal boilerplate
  • Great developer experience with the official tool SvelteKit
  • Easy learning curve, especially for those new to modern JavaScript frameworks

👋 Svelte in Action (Example)​

<script>
  let name = "World";
</script>

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

<input bind:value={name} />
