What text is indexed by search engines?

Question

JavaScript

Let's say I have in the source code of the site the text "Corner wardrobe", which is taken from the database.
But in JS, when I access the page, I change it to "Buy a corner wardrobe".
What text is indexed by the search engine?

Answer 1

Source. Because for all the assurances of search engines, the text that is created in JS is not indexed, unless there is an SSR. Diskus comments in JS are still not indexed.

Answer 2

Do it right right away without crutches on zhs
