            "penrose-new_zealand",

        ]
    }
    ```

  - The third one, `dates`, consists in their last and/or upcoming concert dates.

            ],
            "georgia-usa": [
                "22-08-2019"
            ],
            "los_angeles-usa": [

- This project also focuses on the creation of events and on their visualization.
  - An event-driven system consists in a system that responds to some kind of action triggered by the client, time, or any other factor.

This project will help you learn about :

- Manipulation and storage of data.
- HTML.
- Event creation and display.
  - [Event-driven system](https://medium.com/omarelgabrys-blog/event-driven-systems-cdbe5a4b3d04).
- JSON files and format.

### Instructions

- The backend must be written in **Go**.
- The code must respect the [**good practices**](https://github.com/01-edu/public/blob/master/subjects/good-practices.en.md).
- It is recommended that the code should present a **test file**.
