Advanced Tip: Leverage Laravel's Macroable trait to extend core classes with custom behavior. Using macros, you can add new methods to classes like Collections, Response, or the Query Builder—making repetitive tasks more streamlined and your code more expressive. For example, by defining a macro in a service provider, you can add a custom method to Eloquent Collections that applies common filters or transformations across your application, reducing boilerplate code and promoting reuse.
