JavaScript is a young language. It's been around for 21 years. C has been around for 45 years. I'm sure things will be relatively stable 24 years from now in terms of web development, but then there will be a new medium for writing code with massive churn in commonly-used libraries and techniques. A need to learn new things in a young language will never die. Even C++, which is "only" 34 years old is experiencing massive changes to its syntax and common practices.
