I don't even know what those are, so I suspect I have never done them at all.

My first boss told me many years ago that all functions convert some input into some output and thats all there is, mind you he also told me if I wrote functions that were more than 11 lines long I was doing it wrong...

Generally speaking, your boss was right 
It's certainly a good way to look at code.

When it comes to the DB, it's all crud.

Not sure if it's only filter, map and reduce, but A LOT of programming is just working and transforming collections.
Which makes sense, because what I do (and what a lot of programming is) is collecting data, collections of things basically, and apply some statistics (mostly costs, profits, distances, weights, etc.)

Hmm. We lone wolves in the process control and embedded world will ignore your contention with quiet dignity and grace.

Programming is a repetition of 3 things:
- map data from an external source to some kind of internal representation
- use algorithms to transform properties of the internal representation (change location, persistency, unit conversion, hierarchy..)
- filter and visualize the internal representation in some way
So no, I don't think map, filter and reduce are correct.
Map, filter, transform look better.. but that's just an optical illusion TBH.
In truth, you "map & transform" input into something with persistency and then "transform & filter" to get your output.
The skillful coder will only "map & transform" once per project, and "transform & filter" once per output device.
Just my 2 cents.

Input
Output
Process (Compute)

It was explained to me in the 1970s by those in the know that 90% of the work a computer does is sorting. Nowadays there are objects, classes, thunks and Lambdas, and Map/Filter/Reduce are just new ways of sorting.
I'm retired. There's a nap for that...

If I said that, "I love Microsoft." The flame war would decimate a couple of continents, and dry up an ocean or two. I use Win 10 and 7. I also use two versions of Linux. My son is a developer and he uses Mac. This is just to show I really don't have much of a dog in the race here.
Why does everyone want to waste there time hating MS? Net Market Share reports that 84.57% of desk top operating systems are MS. I know MS. I don't have to spend hours learning more. Linux takes up a chunk of my time learning the directory/file system and how to move around in it. I don't have time for Mac.
I live in a cold, dark place called reality where I have to use what the shop is using and at home I just want to work the Sudoku, watch some electronics how to videos on you tube. I don't care what the platform is.

I have little troubles with Win as I never bought a copy in 26 years, and cured versions come with all the tools to shut the flock up of any updater.
At work there are slightly more troubles but since I'm paid to work 8 hrs/day and no one gives a flock about how I work and how productive I am I simply roll with it.

Legally they were backup copies of the original  and any "cure" was already there I swear, it must be a virus.

I not say "hate," rather "dislike." - less strong.
Briefly why: They are the BMW drivers of the software world.

As In "Big Money Wasted", or "I would not want to own one not under warranty?"
I would tend to agree...
BTW, I am a BASHER of MSFT, simply because I expect more from them.
Also, they get the blame, because 84% of the desktops are suffering from their GOOD and BAD decisions.
We all have stories to tell, because we all have experience with them. And at some point, their bad decisions have crushed us. Programs I wrote 30 years ago should still work. have you tried to run Basica lately? Win3.1 16 bit code? the constant need to refresh working code. Ugghhh.
How about windows 10 no longer liking programs that write program data to a Data folder under the program folder... Ahhh, progress...
So, it's a love hate thing. I love that I can write and sell software that runs on Windows.
But I hate the fact that the definition of "Windows" is too flexible, and that MSFT will make a bonehead change (like assuming everything is a tablet), or try to run a PIG on a phone. And I am left to deal with the problems...
Don't get me started with tweaking the office file formats, and thwarting standards, and giving things away free, until they become popular and competition drops, then gouging... But still not as bad as I feel Oracle has been behaving!

We.... hate the sin not the sinner.
I love windows. I hate that Microsoft is using it to herd us into their "ecosystem" or whatever they call it now.

You hate that a company is trying to use one of their products to get you to buy into their other products? They're monsters!

It's like Beretta vs Glock. Aftermarket for Glock? Basically everyone and their dogs. Aftermarket for Beretta? Only Beretta, low to nigh choice, Italian quality (N/A).

I think one can be neither "in love with," nor, "in hate with," Microsoft, or other mega-tech companies ... but, also, not emotionally indifferent.
To make this more concrete: I can say that I frequently marvel at the depth and power of MS' software tools, like Visual Studio, and the tools in its ecosystem, like ReSharper, PostSharp, etc. But, of course I get frustrated by the speed-bumps you go over putting these tools to use. As someone who "goes way back" in software development, I know these tools are fantastic compared to what we had even ten years ago.
I find it useful to resist "personifying" an entity like MS, to avoid assuming it's like a "someone" who makes mistakes: if I were to analogize MS and person, I'd say it's a "somemany" with multiple personalities, some of whom are schizoid, and most of whom are not aware of each other ... and, this "person's" mistakes are colossal blunders
A state of benevolent equanimity is, of course, fragile, and, may require a purgative rant to release spew ... when broken.

I hate them because I fell in love with WPF only to have them not support or push it.
I hate them because I use Windows Media Center on all TVs in my home and I can no longer get guide data.
I hate them because of their extreme push to migrate to Windows 10.
I hate them because both of my parents computers automatically installed Windows 10 and I had to spend the time reverting it.
I hate them for forcing Cortona, Edge, and all their own applications down my throat.
I hate them for Internet Explorer. My only UI bugs in web apps start with "1. Open IE...".
I hate them for being so late to the party on mobile. Windows Phone was great to develop for. And they blew it.
With all that said... I still run Windows. I still love Visual Studio.
