About This Playground
This collection of tools demonstrates practical JavaScript development and API interaction patterns. All tools run client-side in your browser — no data is sent to external servers (except for the API Tester when you specify an endpoint).
Technologies Used:
- Vanilla JavaScript (ES6+)
- Fetch API for HTTP requests
- Client-side data processing
- Responsive CSS Grid layout
Planned Additions:
- JWT Decoder & Validator
- Hash Generator (MD5, SHA-256)
- Regex Tester
- Network Port Scanner (client-side)
- Color Code Converter
