JSDOM Scraper
No credit card required
Parses the HTML using the JSDOM library, providing the same DOM API as browsers do (e.g. `window`). It is able to process client-side JavaScript without using a real browser. Performance-wise, it stands somewhere between the Cheerio Scraper and the browser scrapers.
