Discussion on: What programming skills, concept, techniques have you learned so far?

Things that were the most influential to me:

• functional programming, immutable data, composing functions
• event-driven patterns
• state machines
• promises, coroutines, threads: asynchronous patterns
• queuing theory, and how it applies to performance
• being a professional developer is about solving problems, sometimes with software. the software itself is a tool
• product-first thinking, of which DDD is a formalization
