I don't think it will die. Just evolve, as it always has. It might not be as trendy/hot as it was a couple of years ago, but it still going to be there. It has a very rich ecosystem around it.
Just like PHP on the server side. We now have cool languages like Node, Go, Scala or Kotlin, yet there's still a strong community of PHP Developers and the language itself keeps evolving and adapting. The community is still vibrant to date.
