There should always be a job available for you that doesn't require writing JavasScript. However, as a counterpoint, I have been writing ruby/javascript for a while now and the last couple of years I agree the JavaScript has taken over my career. I have 0 complaints, I love modern javascript, the ecosystem, the engines, debug tools and everything between. You don't have to like it but lots of people do and lots of high quality software is being made with JavaScript.
Agreed with your counterpoint. I used to try to avoid JavaScript, nowadays I wish I could use it for everything (C++, C#, and some others are still unavoidable for some of my work). Modern JavaScript is my favorite programming language at this time.
