Why is AngularJS poorly indexed by search engines, but ReactJS is good?

Question

JavaScript

When I read that angularjs is poorly indexed by search engines, and reactjs is well, I don’t understand why. And as a separate point, I want to ask if it is possible to write an application in reactjs so that it is not indexed just like in cases with angularjs? And how to make it indexed on reactjs?

Answer 1

search engines do not work well with js in general. a crawler is like a user who has js disabled (actually, things are a bit more complicated and search engines render js, but that's another matter).
Disable javascript in the browser and see what content will be visible on the site with angular and what on the site with react? This is the content search engines will get.
well, react supports server-side rendering, which means that search engines will immediately receive full-fledged html. not a template with no content, in the case of angular.
