Give practical examples."}, {"role": "assistant", "content": "Great, let's explore this together: Regarding web dev: What is REST API and how does it work\n\nThis is an important concept in programming. The key ideas are:\n\n1. The foundational theory involves understanding the core mechanisms at play.\n2. In practice, you'll encounter this in real-world applications where precision matters.\n3. Common misconceptions include oversimplification of the underlying complexity.\n4. Advanced practitioners go deeper by examining edge cases and interactions.\n\nI recommend building up from first principles, trying concrete examples, and referring to primary sources for the most rigorous treatment."}]
