JS Tabby is a Chrome extension developed by Daniel Larkin. It is a free tool that replaces the "New Tab" page with a codepad and console, making it easier to solve problems with JavaScript. With support for ES6, JS Tabby allows users to test and run their code on the fly.

The extension provides a simple and intuitive interface for writing and executing JavaScript code. It is especially useful for developers who frequently work with JavaScript and need a quick and convenient way to test their code without leaving their browser.

If you encounter any bugs or have feedback and suggestions, you can report them through the Github repository associated with JS Tabby. Please note that the developer encourages users to provide feedback and suggestions via the repository, rather than contacting them directly.
