When Debugit is the better choice

Debugit is for JavaScript and TypeScript developers who want to work more confidently and efficiently in existing codebases. Whether you are reviewing a teammate's change, AI-generated code, or an unfamiliar part of the codebase, you need to understand what it does, test its behavior, and spot problems before relying on it.

Practical debugging exercises are a great way to build JavaScript fluency. The explanation after each problem helps deepen your understanding of the JavaScript behavior behind the bug, from language quirks and anti-patterns to asynchronous JavaScript and the event loop.

When LeetCode is the better choice

LeetCode is the better choice when you are preparing for a technical interview centered on algorithms and data structures. It helps you recognize common problem patterns, write a solution under constraints, and explain why your approach is efficient. It is also useful for performance-critical work, where choosing the right data structure or algorithm can directly affect the cost of a feature.
