Surely the best hope for interop is something like WebAssembly - right now if I'm using two compile-to-JS languages it's pretty unlikely they'll be compatible, whereas with WebAssembly there will at least be a common notion of e.g. what an integer is. Hopefully that can translate into a common ABI.

And main reason this hasn't happened is the lack of a good common ABI/runtime. Libraries do get reused cross-language on the JVM or CLR, but only within that platform; outside it only the lowest-common-denominator C ABI exists which means interoperation between high-level languages is basically impossible. Moving everything onto the web is a chance to make that possible.
