Big M notation for an API: how much mental effort does it cost to adapt the code to a new requirement. Good abstractions help you turn M(n^2) into M(n), M(n) into M(1).

Writing DOM mutations by hand is M(n^2) where n is the number of possible states. Declarative rendering is M(n): you only describe the result for each state once.

Abstractions and “patterns” aren’t fundamental to programming. Computers couldn’t care less about them. Abstractions are a coping mechanism for struggling to hold more than 2^3 things in our heads at the same time.

Think about Big M of the abstractions you use, related to the tasks you do most often. Just like Big O, Big M may be optimized for reads, writes, or deletes — but of code itself.

Also this is an interesting paradox: optimizing for O(n) over M(n) locally can lead to worse O(n) in practice globally.https://mobile.twitter.com/dan_abramov/status/1011756333211750408 …

I politely disagree. Computers manipulate electrons and photons. Anything else is an abstraction, often using patterns (e.g. instruction sets) To me, programming is human aspect of constructing computer operations (or programs). So patterns are fundamental to human programming.
-
I don’t disagree with you, it’s a bit like splitting hairs because we have only these brains and can’t even try to “program” differently. But if alien civilization also wrote programs but didn’t need abstractions (or had a different level) I would also call it programming.
-
High level explanations and abstractions are necessary to understand or explain anything about the world. All intelligent people, including aliens, must use them.

If you’re able to accurately simulate a computer in your head, isn’t machine code itself the best explanation?
-
Is your brain RISC or CISC?

Yeah, programming can be with and without abstractions, but whats the point?
We are stupid, so we need abstractions. The better abstractions the less defects.Bedankt, Twitter gebruikt dit om je tijdlijn te verbeteren. Ongedaan makenOngedaan maken

It was far too late in my career when I realized this, well said.
