Googlebot can crawl lots of pages at the same time. It can even render JavaScript. But, as Google's Martin Splitt put it, “JavaScript requires an extra stage in the [crawling and indexing] process, the rendering stage.”

JavaScript can complicate the search engines' ability to read your page, leaving room for error, which could be detrimental for SEO. When a search engine downloads a web document and starts analyzing it, the first thing it does is understand the document type.

Google can crawl JavaScript, but not all JavaScript. That's why it is so important to implement graceful degradation to your webpages. That way, even when the search engine can't render your web pages properly, at least it won't be catastrophic (think Hulu).
