How do you measure that? Do you include only companies with _no_ experience in a particular language before starting a new project using that language? Companies usually continues the language they have an experience with. Except some areas where you don't have much flexibility. Like for AI you chose Python even if you have no experience. Or for a website, you don't have much choices and have to use TS/JS even if you don't like them.
