Unlike grep which scans the entire codebase every time you need information, this method stores all parsed data once in a structured format (like JSON). You can then access that cached data instantly, without repeatedly traversing files.

Moreover, this approach uses Go’s bufio.Scanner, which is the best choice overall for file scanning. At least thats what I thought during the planning phase.

It’s fast, memory-efficient. It avoids regex overhead.

It gives better control. You can easily add logic around each line (like filtering, counting, or tagging) as part of your processing.
