Does Google work with JS recognition in SERPs?

Question

Google

The client asked to improve the site in order to give out in Google search. There are two solutions, one of them is to use JS to display the data. How is the situation with Google rendering pages in JS. Is it possible to use JS to fit some numbers into a text string. Will it be recognized in Google search and will it appear in the search results?

Answer 1

Google doesn't always render js. It is more reliable to give him ready-made html, rendered via SSR. Well, or yes, try and see the saved copy. If this section of code is there, then it is recognized. Well, do not forget that Google, by and large, is not so important what numbers are on the site (unless it is assumed that users will drive exactly these numbers into the search box), it is more important that users receive an answer to their question on your page.

Answer 2

So do it on one page, index it and see

Answer 3

Google can index not only javascript sites, but even texts in pictures (and for example pdf) and voice recognition on video (if it's youtube), but it seems to me that everything is difficult about ranking based on this information, when, in principle, there is little information on request, I I see this information in the output.
On the other hand, this does not always work; I saw a situation when I see the necessary text in the subtitles for the video, but this video is not found in the search. I don’t know exactly how it works, maybe Google is only experimenting with these technologies and only part of the Internet gets into the index.
