`page.$(query)` or `page.$$(queryAll)` to be more specific

https://github.com/GoogleChrome/puppeteer/blob/v1.1.0/docs/a...

yes I've used puppeteer, but I couldn't see where it exposed the page object, but looking closer I saw

HCCrawler.launch({ // Function to be evaluated in browsers evaluatePage: (() => ({ title: $('title').text(), })), // Function to be called with evaluated results from browsers onSuccess: (result => { console.log(result); }), })

which doesn't look that good for my other worry, that you come to a dynamic JS built up page, load the DOM and evaluate in some milliseconds and then that DOM is changed after you've done your incorrect evaluation.
