Templates, or patterns, are reusable solutions to common problems in software design. They provide a standard way to address specific issues, making it easier for developers to create consistent and efficient code. By following these established structures, programmers can save time and reduce errors in their projects. In programming, templates can be found in various forms, such as design patterns and code templates. Design patterns, like the Singleton or Observer patterns, offer proven strategies for organizing code. Code templates, on the other hand, serve as starting points for new projects, ensuring that essential components are included from the outset.
