Read the explanation before looking at code.\r\n\r\n```bash\r\n# Example\r\ncat docs/data_types/data_types.md\r\n```\r\n\r\n### 2. Run and Modify Examples\r\nDon't just read code—run it, modify it, break it, and see what happens.\r\n\r\n```bash\r\ncd src/loops\r\ngo run for_loop.go\r\n# Then edit for_loop.go and experiment\r\n```\r\n\r\n### 3. Use `go fmt` and `go vet`\r\nFormat your code and catch common mistakes:\r\n\r\n```bash\r\ngo fmt ./...\r\ngo vet ./...\r\n```\r\n\r\n### 4. Write Small Programs\r\nAfter each concept, write a small program combining what you learned. This reinforces knowledge.\r\n\r\n### 5. Benchmark and Profile\r\nUse the performance tips to measure your code:\r\n\r\n```bash\r\ngo test -bench=. -benchmem ./...\r\ngo tool pprof\r\n```\r\n\r\n### 6.
