Isn't that exactly the syntax being recommended? Could you explain what exactly in the article is a solution in search of a problem?

Did you read the article? Your comments feel entirely disconnected from its contents - mostly low level piece or things that can replace libraries you probably used anyway

I think there are several reasons. First, the abstraction of a stream of data is useful when a program does more than process a single realtime loop. For example, adding a timeout to a stream of data, switching from one stream processor to another, splitting a stream into two streams or joining two streams into one, and generally all of the patterns that one finds in the Observable pattern, in unix pipes, and more generally event based systems, are modelled better in push and pull based streams than they are in a real time tight loop. Second, for the same reason that looping through an array using map or forEach methods is often favored over a for loop and for loops are often favored over while loops and while loops are favored over goto statements. Which is that it reduces the amount of human managed control flow bookkeeping, which is precisely where humans tend to introduce logic errors. And lastly, because it almost always takes less human effort to write and maintain stream processing code than it does to write and maintain a real time loop against a buffer.

Hopefully this helps! :D

A stream is not necessarily always better than an array, of course it depends on the situation. They are different things. But if you find yourself with a flow of data that you don't want to buffer entirely in memory before you process it and send it elsewhere, a stream-like abstraction can be very helpful.

Streams have backpressure, making it possible for downstream to tell upstream to throttle their streaming. This avoids many issues related to queuing theory.

That also happens automatically, it is abstracted away from the users of streams.

Why is an array better than pointer arithmetic and manually managing memory? Because it's a higher level abstraction that frees you from the low level plumbing and gives you new ways to think and code.

Streams can be piped, split, joined etc. You can do all these things with arrays but you'll be doing a lot of bookkeeping yourself. Also streams have backpressure signalling
