A Development Environment is a set of tools and software that developers use to create, test, and debug applications. It typically includes an integrated development environment (IDE), programming languages, libraries, and frameworks. This environment allows developers to write code efficiently and manage their projects effectively. In a development environment, developers can simulate how their applications will run in the real world. They can also use version control systems like Git to track changes in their code. Overall, a well-configured development environment enhances productivity and helps ensure the quality of the final product.
