What's the hardest programming concept you've ever learned??

@Phnxio Dependency Injections 😅

@Phnxio Memory safety and ownership. Rust humbled me real quick lol

@Phnxio Recursion. I finally understood it when I explained it to myself… using the explanation I gave myself… after explaining it to myself… which only worked once I understood recursion. 😵‍💫

@Phnxio Concurrency (esp. shared-state + subtle races). It *feels* fine until it isn’t. The mental model shift to message-passing / immutability + good observability made it finally click.

@Phnxio Dynamic programming, tbh. It was fun until you start solving multi pattern problems.

@Phnxio OOPS concepts in java.

@Phnxio pointers

@Phnxio Red black trees, it was so abstract for me, paradoxically I immediately understood graphs compared to trees

@Phnxio Beautiful soup 😆

@Phnxio As a kid it was definitely pointers in cpp. "Wtf do you mean I pass a memory address?"

@Phnxio Graph

@Phnxio promises in JS

@Phnxio Pointers in C++… oh boy 🤯 I still sometimes stare at my code wondering where exactly that memory is pointing 😂

@Phnxio async programming still gives me nightmares

@Phnxio Babylon js
