title: Executing scraped JavaScript with cheerio
body: <p>I have a web page in which there are some JS APIs that don't alter the dom, but return some numbers.
  I'd like to write a NodeJS application that downloads such pages and executes those functions in the context of the downloaded page.</p>
  
  <p>I was looking at cheerio for page scraping.. but while I see how easy is it to navigate and manipulate the DOM with it, I don't see any access to running the page functions. Is it possible to do it?</p>
  
  <p>Should I look, instead, at jsdom?</p>
  
  <p>Thanks</p>
