06 - Control Flow (If, Else If & Else Statements & Each Loop) in Svelte 5
Welcome to this comprehensive guide on Control Flow in Svelte 5! 🚀
In this video, you’ll learn how to build dynamic, reactive UIs using Svelte’s powerful templating syntax. Whether you’re new to Svelte or upgrading from a previous version, this tutorial will equip you with the tools to handle conditional rendering, list iteration, and user interactions like a pro.

What You’ll Learn:
• Conditional Rendering: Use if blocks to show/hide elements based on conditions, and chain else/else-if statements for multi-case logic.
• Loops: Master each blocks to iterate over arrays and objects, and discover why the key attribute is critical for performance.
• Event Handling: Bind user actions like clicks and form submissions to reactive state updates.
• Real-World Example: Build a Todo List app from scratch to see these concepts in action.
