Remove Multiple New Lines with JavaScript

My task is converting the blog post, in whatever format it's provided in (HTML, Markdown, PDF, Google Doc, etc.), to HTML for my blog, which can sometimes get messy. I employ a host of regular expressions to fix these formatting issues. And the number one problem? Loads of extra new lines (\n).

content.replace(/[\r\n]+/g, '\n'); // Just one new line
content.replace(/[\r\n]+/g, '\n\n'); // "document" formatting, more elegant
With the dozens of extra lines gone it's much easier to work with the content!

David,
I’m more inclined to use something like:
Only there always seems to be some extra whitespace between those newlines. If you don’t want to loose the tabs on the next line then this works just as well
