Good job, I left a couple of comments, could you satisfy them?

Try running your wc sample-files/* next to the real wc sample-files/*. How many lines does each print? What does the real tool add at the bottom when you hand it more than one file - and where would that value need to be built up in your loop?

Put your cat -n sample-files/1.txt beside the real one and look at the space before the 1. What's different about how the number sits in the column? You already solved this exact thing somewhere else in this same file — where?

What character does real cat place between the line number and the text — is it spaces, or something else? Try copying a line of real cat -b output and your own into the same file; do they line up?

Run ls -1 -a sample-files for real and compare it to yours, line by line. Which two entries does the real one list that yours doesn't? Does fs.readdirSync ever return those, and if not, where could they come from?

| let totalLines = text.split("\n").length - 1; | ||
| let totalWords = text.trim().split(/\s+/).length; |

What would totalWords come out as for a completely empty file, given "".split(/\s+/)? What does real wc report for one? It's not in the test set — but is the count you'd produce the one you'd want?
