Does Googlebot execute JavaScript?
Googlebot skips rendering and JavaScript execution if the meta robots tag initially contains noindex . If there is a possibility that you do want the page indexed, don’t use a noindex tag in the original page code.

How to know how much JavaScript Googlebot can read, crawl and index?
We wanted to know how much JavaScript Googlebot could read, crawl and index. To achieve that, we built a website – http://jsseo.expert. Each subpage had content generated by different JavaScript frameworks. We tracked server logs, crawling, and indexing to find which frameworks are fully crawlable and indexable by Google.
When did Google start crawling the web with JavaScript?
As early as 2008, Google was successfully crawling JavaScript, but probably in a limited fashion.
