Do you ever heard about service classes ?
Do we need actually need it ?
We can code with or without service classes.But when we use service classes,It all matters when we code with intention of good readability,We don't want to code that just works,Our code must be beautiful enough to read by other developers, especially our senior dev.
Service classes allows us to write business logic in one place and app logic in another place,What is actually business logic
?
Business logic is nothing but, how we verify the registered user, or how we calculate our shipping cost.

Professional tools such as salon chairs, styling stations, hairdryers, and shampoo units streamline the hairstyling process, allowing stylists to serve more clients in less time. Adjustable salon chairs ensure clients are seated comfortably while hairstylists work efficiently without straining their backs with hair salon equipment . Similarly, high-performance hairdryers and styling tools speed up drying and styling times, reducing wait times for clients and increasing daily appointments.
