‫(gentle electronic music)
‫So we learned before that Node.js
‫is all about asynchronous code,
‫which was traditionally implemented
‫using callback functions, right?
‫However, in modern JavaScript,
‫we now have some better tools
‫to deal with asynchronous code,
‫and these tools are Promises and Async/Await.
‫So I will use Promises and Async/Await
‫in this entire course now,
‫well, because, that's just the way
‫modern Node.js code is written,
‫and so if you're not entirely familiar with these new tools,
‫well, then please go ahead and watch this short section
‫which will bring you up to speed
‫with asynchronous JavaScript.
‫But of course, if you already know Promises and Async/Await,
‫then feel free to just entirely skip this section.
