> Good async frameworks can handle these better, but they typically require some form of cancellation, and my understanding is that that's notably absent from JavaScript & Go's async primitives. Go added cancellation support to the standard library at 1.7. I don't like its coupling with contexts, but the implementation is solid and supported throughout most blocking operations, so this statement is patently untrue for Go. JavaScript really doesn't have a standard way for doing cancellation, which is a shame.
