The number of views of questions on Stack Overflow is a bad metric to measure language popularity. This metric combines popularity and complexity/unintuitiveness. If a language is half as popular but twice as complex (or unintuitive) as another language, then it will get the same number of questions and same number of views. If the language is becoming more fragmented; more different kinds of frameworks and tools then it will translate to more questions on stack overflow. Fragmentation of the language is not necessarily a good (or bad) thing but it has nothing to do with the popularity of the language. But definitely the JavaScript ecosystem is pretty homogeneous at the moment (ReactJS or VueJS on the front end and Node.js on the backend).
