How to Send Variables From JS into Go?

[KiddoV]

Pass variables from Go to JS is easy with Events.

//JS
window.runtime.EventsOn("ReceiveData", function(...args) {
    console.log("Data from Go: ", ...args);    // Data from Go: data from go
});

//Go
runtime.EventsEmit(a.ctx, "ReceiveData", "data", "from", "go");

---

I am not sure how to do the opposite way? JS => Go

//JS
window.runtime.EventsOn("SendData" {
    let stringFromJS = "Hello Go!";
    return stringFromJS
});

//Go
value := runtime.EventsEmit(a.ctx, "SendData");    //Of course it doesn't work this way

So how do I send a value from JS in Go?
Thanks,

Same way 😀

How do I pass or get the ctx in JS side? Is it in window.ctx or something?
JS Signature: EventsEmit(ctx context, optionalData function(optionalData?: any))

Docs fail. Fixed 🙏
