What's the best way of scraping data from a website? [closed]
...or this problem. Since you would rather not learn a new language and you already know Javascript I would definitely suggest sticking with JS. I have not used pjscrape but it looks quite good from a quick read of their docs. It's well suited and implements an excellent solution to the problem I descr...

Call to initialize a particular ID with a Loader. If this ID already
