I'd say that JSON is suitable in environments where reading the structure into memory is The Thing To Do.
If you cannot read the whole thing into memory, maybe JSON isn't for you Smile | :)

This, of course, assumes that JSON is suitable at all.

But for a general comment: The very idea of a tagged record structure is to be independent of ordering. If the ordering where fixed according to some schema, an array would probably be a better choice. Then you could omit the tags altogether, saving both space and processing.

The entire world of IoT would scarcely exist online if that were the case.

But something I enjoy this much?

My core nature is not "software developer"

It's "builder"

I like to make things. The reason I got into software is when I was very young I was building simple digital circuits but i didn't have money to buy the neverending list of equipment and supplies to keep up the hobby, so I got into software, which required nothing upfront (at the time) but effort. I fell in love with it and just never stopped.

But ultimately I like to build. Under slightly different circumstances I could have been a metal fabricator and/or engineer.

The IoT stuff incorporates some of that physicality that I like.

They're "key value pairs" ... no order implied. XML has paths. That's why XML is "more perfect".

XML also does not impose order.

Well, obviously the user should be responsible for specifying the order of the desired fields and not you.

With JSON *nobody* gets to specify the order. That makes them suitable for putting in things like std::unordered_map, but not so great for sequential forward only queries.

Only because you're not using it as intended.
There's nothing that stops you from defining a new ordered JSON-standard. I mean, another standard is just what we need isn't it. Smile | :)

I mean, I don't know that JSON wasn't *intended* for low memory environments, but I could get behind the idea that it wasn't designed for them.

Fair enough.
I see it this way, JSON was intended to be used with Javascript. Javascript is anything but low memory! Intentional or not.

Herself asked me to play some Christmas music in the background. We have a Yamaha sound bar under the TV that can be set to use Bluetooth as its sound input. So I thought it would great to send music from my laptop to the sound bar, as its sound quality is fantastic.

I must have tried for more than an hour to get the two devices to connect via Bluetooth, with no luck. In the end in sheer desperation, I decided to read the Yamaha manual - and there it was plain as day: If you have difficulty to connect, you may have another Bluetooth device too close to the sound bar. Yes! I turned off my desktop's (which was nearby) Bluetooth and the sound bar immediately connected to the laptop. Aaaaargh!

So she asked me why I did not read the manual in the first place? I said: "I am an engineer, I shouldn't have to read manuals."

She said: "For a clever engineer you are rather stupid!" So here I sit listening to Christmas music with a deflated ego! Sigh | :sigh:

For something a bit different, try John Fahey's Christmas music played on guitar : https://www.amazon.com/s?k=john+fahey&ref=nb_sb_noss_1[^]. It's really very, very good if you like acoustic guitar music.

A piece of trivia : in the movie "A Clockwork Orange", Alex goes into a record store and at the counter there are two albums displayed. One is the soundtrack of "2001, A Space Odyssey" and the other is a John Fahey record.

I could't see any preview (or pre-listen) on Amazon, but I'll take one note of the name, and try to find a preview somehwere else.

One of my primary Christmas record is another acoustic guitar one - Jul I Gammel Tid by Rolf Lislevand[^] ("Chistmas on the old days").

In this case it is somewhat unfortunate that Amazon tends to pick their 30 sec samples from the start, or early part, of the track. That is when the theme is introduced, and you do not get an opportunity to hear how the player elaborates on it, makes his variations, plays around it, the way old musicians did. A few of the tracks chains together two or three tunes in a beautiful way, that you will not get a chance to hear (without buying the album).

Lislevand may be the very best baroque guitar player of today, knowing more about the historically "correct" interpretation than most others. Yet, he is very playful: Listen to the way his group goes completely crazy with old "Tourdion" on the album "Diminitio"! (Here, the first 30 seconds reveal none of the crazyness Smile | :)

My missus is the opposite, she hates it when I take the time to read the manual, which is the second thing I usually do, the first is power cycle. Her patience, like many, has been tossed aside by her need for instant gratification. If, after reading the manual and attempting the troubleshooting, it still doesn't work, well then my patience is gone, and a device smashing I will go. That kind of crap I don't need.

Just say "yes dear" and be done with it.

If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.
