+// MARKDOWN PARSER - REFACTORED VERSION
+//
+// Refactored to improve readability and maintainability while preserving exact functionality.
+// Key improvements:
+// 1. More descriptive function names (parse__ -> parseBoldText, parse_ -> parseItalicText, etc.)
+// 2. Clearer variable names (list -> isInList, count -> hashCount)
+// 3. Better separation of concerns with dedicated functions for each parsing task
+// 4. Comprehensive comments explaining the purpose and logic of each function
+// 5. Improved control flow with clearer priority order for parsing
+// 6. Enhanced documentation with JSDoc comments
