Description: A development server is a local environment that allows developers to efficiently test and develop applications. In the context of modern web development, this server facilitates the quick and easy creation and testing of applications. By using a development server, programmers can see changes in real-time without the need for complicated configurations or deployments to a remote server. This type of server typically includes features like hot reloading, meaning any changes in the code are instantly reflected in the browser, thus enhancing productivity. Additionally, the development server is usually optimized to handle errors and provide clear debugging messages, helping developers identify and resolve issues more effectively. In summary, the development server is an essential tool in the application development workflow, enabling an agile and efficient development cycle.
