The main purpose of an integrated development environment (IDE) is to provide developers with a comprehensive set of tools to facilitate software development. An IDE combines essential features such as a code editor, debugger, and build automation tools within a single application, streamlining the coding process. With features like syntax highlighting, code completion, and version control integration, IDEs enhance programmer productivity and efficiency. They often support multiple programming languages and offer customizable configurations, making it easier for developers to manage projects and collaborate effectively.
