There is a non trivial overlap between the people present for the creation of C (which followed B) and the creation of Go - so there may have been something weird in the water at Bell Labs sometime around 1980. D just followed the existing convention and C++ started out as an extension on top of C. JavaScript on the other hand was an entirely intentional marketing move. Only issue was that the programmer they hired to create the language wasn't on the Java hype train.
