What is Refraction for VS Code?

Refraction is a VS Code extension that identifies coding errors and suggests improvements as you work. It analyses your code in real-time, flagging issues before they become problems and recommending ways to enhance readability and performance. The tool integrates directly into Visual Studio Code, making it accessible to developers using popular programming languages. It works across different coding styles and frameworks, helping both junior developers learn better practices and experienced ones catch subtle issues they might otherwise miss.
