I've noticed that the code for printing lines (with or without numbers) is repeated in a few places inside your forEach loop. If you ever wanted to change how lines are printed, you'd have to update it in multiple spots. Can you think of a way to extract this logic into a helper function, so you only need to update it in one place if requirements change?

You have a variable called globalLineCounter declared outside of any function, which means it exists for the whole script. While this works for your use case, can you think of any potential issues if you wanted to reuse your printFile function in another context, or if you wanted to run multiple file prints in parallel? How might you limit the scope of this variable to avoid unexpected side effects?

The variable filePatterns might suggest that it stores patterns (like wildcards), but in your code it actually just stores file names. Do you think a name like fileNames or files would make the code's intent clearer to someone reading it for the first time?

How could you group this logic into a helper function so that you only need to update it in one place if you want to change the output format?

The variable 'globalLineCounter' is declared at the top level, so it is shared across all function calls and files processed. This works for your current use case, but can you think of any situations where having a global variable like this might cause unexpected behavior, especially if you wanted to reuse your printFile function elsewhere or in a different context?

The name 'filePatterns' might make a reader think it stores wildcard patterns (like '*.txt'), but it actually just stores file names. Would a name like 'fileNames' or 'files' be clearer for someone reading your code?

Your function 'listDirectory' takes a parameter called 'dirPath', but sometimes you might pass it a file name (if the user gives a file instead of a directory). Do you think this name could be misleading for someone reading your code? What name might better reflect what the function expects?
