The Rise of Vibe Coding

“Vibe coding” is a term that emerged in 2024-2025 describing a new programming paradigm where developers guide AI tools through natural language while maintaining creative direction.

Vibe Coding Principles:
├── Describe intent, not implementation
├── Iterate on AI suggestions
├── Focus on architecture, not syntax
├── Trust the AI for boilerplate
└── Review carefully, don't just accept
