Data extraction has many forms and can be complicated. From Preventing your IP from getting banned to bypassing the captchas, to parsing the source correctly, headerless chrome for javascript rendering, data cleaning, and then generating the data in a usable format, there is a lot of effort that goes in. I have been scraping data from the web for over 8 years. We used web scraping for tracking the prices of other hotel booking vendors. So, when our competitor lowers his prices we get a notification to lower our prices to from our cron web scrapers.

You've probably heard about Heroku by now, but do you really know how Heroku works and when it should be a consideration?
ES6 came with many new features, but one of the best features was the official introduction of Promises. Promises allow you to write clean non-callback-centric code without ever having to worry about callback hell. Even if you never write your own promise, knowing how they work is incredibly important, since many newer parts of the JavaScript API use promises instead of callbacks. The core idea behind promises is that a promise represents the result of an asynchronous operation.
I've been using Handlebars in Node.js apps for a long time now and while it always gets the job done, sometimes I find it awkward to use. In particular I miss being able to use expressions and flexible logic flow directly in the templates.I know there's an argument for keeping logic and views separate and that views should be "logicless", but sometimes you just want a bit more control. The existence of libraries like Swag, suggests that I'm not alone here so I got to thinking...
