We'll cover the following...
I think you have heard about layered architecture of some kind. Nowadays, most applications are built by utilizing layers. If you are new to this concept, make sure to become familiar with layers by reading about this topic (see here).
Layers help separate concerns in the codebase by providing guardrails to engineers when implementing requirements. Guardrails mean built-in guidance, less confusion, and more time to focus on more important things, such as building and delivering features. Also, layers are part of an established language that helps communicate across technical personnel about plans for implementing code or placing individual components under specific packages or projects of solution.
Because of the mentioned values, I recommend that you think about layers before you start writing code. When ...
