This is rapidly reversing as the javascript ecosystem has increasingly adopted typescript in the last two years. I, for one, refuse to start a new front end without it, and the only other js dev I've spoken with recently who disagreed had never actually used typescript and didn't want to "write a bunch of interfaces like java".

I would not say fell out of use, most enterprise-grade apis, old or new, will have one -- think bank/government/big corp. GraphQL is not there yet - as other commenters pointed out the tooling is not good enough outside JS world, security is complicated on the service side, and the protocol is just to young - the official release is two years ago, so it may start appearing just around now.
