Question

React

Here is a live example https://dodopizza.ru/ We click on pizza, in the modal window we get data on pizza. Why arguments in the address bar? As far as I understand, here on click we get the id of the pizza, and we can send a request to the api. What role can the argument in the address bar play here?

Answer 1

In this case, the parameters in the address bar are needed so that the user can copy the link to the selected product. It may also be necessary for the correct indexing of the site by search engines.
