Question

JavaScript

Is it true that with js the site becomes vulnerable and Google and other search engines except Yandex already omit such sites in the search results?
1. Is it true?
2. How much is true?
3. And what about this (if true), should I use js?
Please detail if possible ... pros, cons and a real perspective on the future.
Thank you.

Answer 2

Agree, brat. For example, the so-called SPA-sites, which are more popular in the West, and which are actively appearing with us, are also based on js technology, and there are no pessimizations about them either.
