Tutorial 17: Build a Real-Time Character Counter in JavaScript (FreeCodeCamp Project)
⌨️ In this video, I build a real-time character counter app using JavaScript — completed in under 30 minutes! This is Tutorial 17 in my FreeCodeCamp JavaScript series, where I document my journey to becoming a full-stack developer.
💡 What You'll Learn:
DOM manipulation using getElementById
Realtime updates using the input event
Dynamic feedback with textContent and styling
How to enforce input limits with string slicing
Visual error handling (turning red when limit exceeded)
⚙️ Project Overview:
You're building a simple but powerful tool: a text area with a live character count that stops accepting input after 50 characters and gives visual feedback if the limit is passed.
🙌 If you’re learning JavaScript and want to apply your skills to small, meaningful projects — this video is for you.
