Presenter first (software approach)

Imagine you want to build a sandcastle. First, you have to gather all the materials you need to build it. Next, you need to decide on the design of the sandcastle. Once you have these things ready, you can start building.

Presenter First is a software approach that uses this same idea. It helps programmers build software in a way that is organized and efficient. It starts by focusing on what the program does, rather than how it is going to do it.

The first step is to create a presenter, which is like the design of the sandcastle. The presenter is responsible for managing the user interface and controlling how the user interacts with the program. Once you have the presenter, you can start gathering all the materials you need to build the program.

Next, you need to create a view, which is like the shape and size of the sandcastle. The view is responsible for displaying the information to the user, and it communicates with the presenter to get the data it needs.

Finally, you need to create a model, which is like the sand you use to build the sandcastle. The model is responsible for storing and managing the data used by the program.

With Presenter First, you start by creating the presenter, which helps you organize your program and make sure it is easy to use. By focusing on the presenter first, you ensure that the rest of the program is built to meet the needs of the user. Just like building a sandcastle, Presenter First helps you create something that is both functional and enjoyable to use.
