@p42ai makes refactoring a ton of fun ❤️ 

I really missed all those powerful refactoring commands PHP Storm had. @p42ai is slowly filling that gap. Give it a try, it's awesome!

Now I can be more productive without refactoring my code by hand. Such a time saver!

Edit code effectively

Manually editing your JavaScript code is often cumbersome and error-prone. With the JS Assistant, you can use automated code actions to modify your code accurately on a structural level and focus on what change you want to make, not what to type.

Improve your code

It is easy to miss potential improvements that could make your code more readable and maintainable.

Modernize your projects

Refactor safely

Refactorings, especially those performed manually, can easily break existing functionality or introduce bugs.

Monitor your GitHub repositories

Updates to GitHub repositories can come from many places, and it is easy for low-quality code to slip in. The JS Assistant can monitor your GitHub repositories and their pull requests and let you know when there are suggestions for improvement.

Legacy code is a growing problem in many JavaScript products. I've created the JS Assistant to help developers work effectively in complex real-world code bases.
