How to do multiple output in AJAX?

Question

AJAX

Well, in general, I figured out AJAX at the hello word level, and a question appeared. For example, I have a button with AJAX and when I click it, I would normally get just the response given to me by the page. But what if I want the page to tell me its status when performing each operation from the set.
I click on the "add data" button and somewhere on the main page I get info in the form of a log:
-> connecting to the database
-> entering data
-> successfully!
How can I implement this?

Answer 1

Return from AJAX not "just a response", but "an array of just responses in JSON format", that's all, as easy as shelling pears.

Answer 2

Use JSON arrays.
