Great job formatting the COMPANIES_TABLE_HEADERS array to have each item on a new line. It improves readability. However, it seems that the COMPANY_NAME_FIELD_NAME constant was changed from company_name to name. Please confirm if this was intentional.

It was intentional! Based on my understanding, it is the fix for the undefined company name. It is based on db.json fields, where the name field is the company name not company_name. However, let me know if I'm not thinking correctly 😄
