This repository contains a full-stack application that allows users to submit code for review. The backend is built with Node.js and Express, while the frontend is built with React and Vite.
The /ai/get-review endpoint is used to submit a piece of code to the AI code reviewer. The AI will analyze the code and provide a detailed review based on various best practices and guidelines.

Status: ${response.status});\n return await response.json();\n } catch (error) {\n console.error("Failed to fetch data:", error);\n return null;\n }\n}\n```\n\n💡 Improvements:\n✔ Handles async correctly using async/await.\n✔ Adds error handling to prevent crashes.\n✔ Returns `null` instead of breaking execution.\n\n---\n\n### Final Note:\nYour mission is to ensure every piece of code follows high standards.\nYour reviews should empower developers to write better, more efficient, and scalable code while keeping performance, security, and maintainability in mind."
