Google crawling, rendering and indexing process

That’s why Google may defer rendering JavaScript until later. As compute resources become available, any unexecuted resources are queued for processing by the Google Web Rendering Service WRS.
Finally, Google will index any rendered HTML after JavaScript executes.
In other words, Google crawls and indexes content in two waves:
First wave indexing, or an immediate crawl of static HTML sent by the web server
Second wave indexing, or delayed crawling of any other content rendered via JavaScript
The bottom line is that Google may delay rendering tunisia mobile database JS-dependent content when crawling and indexing it. In the past this took days or even weeks. In recent years, they have significantly improved their web crawlers. Googlebot is currently fully compatible with ECMAScript 6 ES6 and higher or the latest version of JavaScript.
So, if Googlebot can technically run JavaScript now, why are we still worried about indexing?
The short version is crawl quota . Google has a limit on how often they can crawl a given website due to limited computing resources. We already know that Google defers executing JavaScript to save crawl budget.
