> Due to its single-threaded nature, Node.js was never a good choice for compute-heavy workloads, though, and now that capable nonblocking frameworks also exist on other platforms — some with elegant, modern APIs — performance is no longer a reason to choose Node.js.

But do these other frameworks give you the simplicity of sharing code and using the same language in for fe and be ?

For me the performance of Node BE applications is just a nice bonus, for having consistent development environment with huge library of radily available packages.
