Re: Apache vs Express for Node

But if you don't understand sync/async and how it works in a specific
language, how do you know to even use promises, callbacks or "await"? :)

I know, you'll figure it out eventually when googling why your function
isn't working how you expect it and enter the whole new world of async
calls.

But that still doesn't answer the question if understanding the complexity
described in the video is a prerequisite to be able to put together
applications that perform their best.

Javascript before ES2015 was much more complicated. There are new features
that either exist or are coming that make Javascript work in a more
"visibly procedural" fashion. Here's an example of the "await" keyword:

var customer = await getCustomer();
var invoices = await getInvoices(customer.id);
var tickets = await getTickets(customer.id);

The above code looks very normal. To accomplish this in traditional async
fashion would be more busy and harder to understand.
