Some problems have already been solved, and code has likely been written to solve similar tasks to the ones that you’re trying to solve. It’s highly unlikely that you’ll have to start a task by implementing code to do everything from scratch. In any language, libraries exist that you can use to help you code tasks in a modular way: by building upon ...
