The "Inner Loop" refers to a specific part of the software development process where developers focus on writing, testing, and refining code. This loop emphasizes rapid feedback, allowing programmers to quickly identify and fix issues in their work. By continuously iterating on their code, developers can enhance functionality and improve overall software quality. In the context of modern development practices, the Inner Loop often involves tools and techniques such as version control, automated testing, and continuous integration. These elements help streamline the development process, making it easier for teams to collaborate and deliver high-quality software efficiently.
