TUTO 24: I Built a Voting Poll App with JavaScript! (FreeCodeCamp Challenge)

Welcome to TUTO 24 in my hands-on JavaScript series! In this video, I show you how to build a real-time Voting System App using JavaScript — no frameworks, just raw logic. This project is part of the FreeCodeCamp curriculum and my journey to becoming a fullstack developer. 📺 Watch the full JavaScript Challenge Playlist here: 👉https://www.youtube.com/playlist?list=PLPbILVuc6xlR04ICAkVn8g01w-HP4c5SR 🧠 What You’ll Learn: How to use JavaScript Maps and Sets How to prevent duplicate votes How to handle input validation How to dynamically track and display results Master functions, conditional logic, and template strings 🗳️ What the App Does: ✅ Add a new poll option ✅ Vote for any option ✅ Reject repeated votes ✅ Show vote counts in real-time We’ll walk through how to: Initialize the poll using a Map Track unique voters using a Set Add voting options and cast votes with functions like addOption() and vote() Display live results using displayResult() and forEach() 🌟 Inspiration of the Day: This tutorial opens with the story of Alex Ravali, one of the engineers behind GitHub Copilot. He started with struggles — just like many of us — but kept building. Today, he’s helping millions of devs write better code. Your current project could be your future breakthrough. ❤️ If You’re Learning to Code: Like 👍 | Subscribe 🔔 | Comment 💬 This channel is about showing up daily, making real projects, and growing together.
