How I Vibe-Coded a Fast Client-Side Word Counter Tool using AI

Hey DEV community! 👋

I wanted to share a quick project I built using AI-assisted development (Vibe Coding): a lightweight, real-time Online Word Counter Tool.

As an SEO specialist, I often need quick text analysis (word count, reading time, character limits). Instead of using bloated third-party sites, I decided to build one using pure JS/PHP with AI guidance.

💡 Key Features Built:

Real-time word, character, sentence, and paragraph counting.
Estimated reading & speaking time calculations.
Clean, fast, and 100% client-side text processing.

🛠️ What I Learned (Vibe Coding Perspective):

Regex handling: Fine-tuning word breaking algorithms for edge cases (hyphenated words, special symbols, multi-language characters).
DOM performance: Ensuring smooth typing without lag when processing large documents (>10,000 words).
