one example of someone who claims to use only javascript. I don't even see how this is possible. How do you deploy your javascript?
Perhaps they hand it off to the next person in the work chain? Most larger IT shops divide up their development and deployment staff along technology and language lines - it makes recruitment easier for the managers who only need to rattle off a list of languages in their job ads, and managers can better control their staff by withholding access to technologies perceived as desirable to work on.
Perhaps you ask this question because you work in the new-fangled full-stack area where one person does everything. IMO the "DevOps" doctrine is a huge step backwards for business integrity. The doctrine for IT shops previously was to keep separate the people with access to the data and those with access to the code, hence "Development" and "Operations" were two separate areas. Creating "DevOps" people who can change both the data and the code in the name of full-stack processes opens the door up to large-scale fraud by workers of their employers' data and even cash.
