How to get the category id when clicking on a category?

Question

React

Good evening everyone. I am writing a sample application in react. https://yurajun.github.io/react-test
The crux of the matter. How to get the category id when clicking on a category (left column)?
When I click on the phone and go to this page, I can easily get the id from match.params.id, but I can't handle the category. (I can't get the id from the match.params object)
This object is displayed in the console every time I click.
The application code can be viewed in the console in the sources section in the left column in the webpack folder in the subfolder " ."
The script folder is the input to the application
The app folder is the main blocks.
The application has a minimum of code to make it easier to understand. I understand how difficult it is to understand a large application.
Thanks in advance.

Answer 1

Because match.params in categories does not and cannot contain the category id, since there are several categories and their id are contained in the categories array passed to the component
