Spaced Repetition for Programmers: Remember Code Forever
"Use it or lose it" is the curse of programming. You learn a framework, move to a new project, and 6 months later you've forgotten everything.
Why Spaced Repetition Works for Programming
Software engineering requires two types of knowledge: Conceptual (Systems design, patterns) and Syntactic (API methods, regex).
You don't need to memorize everything, but you need to memorize enough to be fluent. Looking up `array.splice` vs `array.slice` every single time breaks your flow state. Spaced repetition keeps these primitives in your cache (L1 memory).
What to Put in Programming Flashcards
Do NOT memorize entire blocks of code. Memorize patterns and primitives.
✅ Good Card
Q: JS: Remove last element from array?
A: .pop() (Mutates array)
❌ Bad Card
Q: Write a function to sort a list...
(Too complex, multiple steps)
Integration with Workflow
- Documentation: When reading docs, don't just skim. Create cards for key concepts immediately.
- Bugs: When you fix a bug, make a card asking "What caused the bug in module X?" to prevent regression in your mental model.
- Standard Library: Memorize the standard library of your primary language. It makes you a wizard in code reviews.
Spaced Repetition Tools for Developers
Developers love efficiency. Anki is popular, but its UI is painful.
SpaceRep is the tool for developers who value their time. Instead of managing yet another "inbox" of tasks, SpaceRep pushes your review sessions to your Google Calendar. Treat learning like a meeting with yourself.
