I may be saying this with incorrect terminology so correct me if I'm wrong please.

Here's what I want to do: I'm trying to scrape a website's comments section but the comments are loaded via an ajax call after the page has fully loaded. When I try to scrape the HTML from the site via: 

```
res, err:= http.Get(url)
if err != nil {
    // handle error
}
defer res.Body.Close()

```

But it obviously gets the html before the ajax call. How do I go about getting the html after the ajax call?

This is completely off the top of my head, but would I need to basically create a js-renderer in code for this? My guess is that the JS needs to execute somehow. Any suggestions / libraries / examples on how to go about this? I'd prefer this to be in go but it could be realistically in any language.
