Does Google crawl with JavaScript
Google processes JavaScript web apps in three main phases: Crawling. Rendering. Indexing.
Can Google follow JavaScript links
When Googlebot renders a page, it executes JavaScript and then discovers the links generated from JavaScript, too. It's worth mentioning that link discovery can happen twice: Before and after JavaScript executed, so having your links in the initial server response allows Googlebot to discover your links a bit faster.
Can Google index JavaScript content
As you can see, Google can index JavaScript content on some websites much better than others. This means that these issues are self-induced and can be avoided. Keep reading to learn how. It's also important to know that indexing content isn't guaranteed even in the case of HTML websites.

How does Google crawl
Crawling: Google searches the web with automated programs called crawlers, looking for pages that are new or updated. Google stores those page addresses (or page URLs) in a big list to look at later. We find pages by many different methods, but the main method is following links from pages that we already know about.

Is JavaScript getting replaced
While it is unlikely that JavaScript will be completely replaced by WebAssembly, it can be used to perform complex computations at near-native speeds, interact with other programming languages, and provide improved security and sandboxing.
