I have a pet theory about that. I think it based on two factors: 1. the size of the community, JavaScript popularity is huge, it's probably the biggest programming community in the world, even the not so popular frameworks have a bigger community then the biggest frameworks in other popular languages (as a not at all accurate measurement, see vue.js and Python's django github stars/followers). If you look at js frameworks/methodologies/libraries compared to the sum of the other languages' frameworks then the pace of change in Javascript compared to how many people use it is not as bad. I had a similar experience with Java when it was the king of the web frameworks - JSP, JSX, JSF, Spring MVC, Struts, Stripe, Wicket and a dozen others. Java was big enough to contain all of these frameworks, and it was big enough for people to support new ideas rather then iterate on existing ones. I'm not familiar with C/C++ enough, but I think it has a similar amount of change to Java (which is somewhat less the JS) 2. the other big factor is how decentralized it is - JS is extremely decentralized, there are tons of big organizations contributing to it's advancement, to frameworks even building their own compilers (all the browsers). Java is very similar in this regard, even in their governing model (a collection of companies that decide on standards together, though Java has drifted from that model with Oracle's lead lately). C# is the opposite, it's one of the biggest languages but doesn't have a lot of change in it - everything is dictated by the central authority (Microsoft) and competing frameworks that don't get popular enough. There are other factors of course, but I think most of those can be seen in other languages with less change, and are less relevant overall.
