How to make website logic?

Question

Angular

It is planned to make a site with different logic and so on. The screenshot shows what you want to achieve. The elements will be loaded from the database, and then when clicked, the location on the map will be indicated, and the description of the "task" will be added below. There will be a lot of similar things on the site with different logic. How to simplify / automate the solution of this kind of tasks?
PS I think that this can be done with some framework, such as Angular, etc., but I don’t know how to work with this. I would like to understand how to solve such problems (for example, as in the screenshot), preferably with an example.

Everything here is, in fact, very simple:
1. Learning to work with a framework like Angular and so on.
2. An understanding of many things comes, including how to solve such problems.
3. PROFIT
In addition to the client, you will also need an API service that will return data from the database.

Answer 2

The most obvious solution is to call the get_curr_rates function directly in the handlers
