Performance estimator scores complexity and suggests fixes. Interactive visualizer makes event loops, closures, and async code click. AST explorer shows code structure visually. Refactoring engine with 5 modes. Bug hunting game. Interview prep from Junior to Staff Engineer. Built for developers who learn by doing. No sign-up required.
I built JSCodeCraft because I was tired of switching between 10 different tabs to review, analyze, and understand JavaScript code.
Every developer tools site does one thing well. I wanted one place that does everything — analysis, visualization, refactoring, and learning.
The static analyzer catches real issues. The visualizer makes async code finally click. The refactoring engine shows you better patterns. And the interview prep actually prepares you for real conversations.
It started as a side project and turned into something I use daily. I'd love to hear what you think — what tools would you add next?
