Description Kasper Isager Dalsgarð 2023-01-13 02:13:03 PST 
The public JavaScriptCore C API is currently missing functions for accessing the state and result of a promise. The private C++ APIs are already there:

https://github.com/WebKit/WebKit/blob/2c3591d6db31967955f974e615d986177db22774/Source/JavaScriptCore/runtime/JSPromise.h#L75-L76

It would also be great with a function for testing if a value is a promise, such as JSValueIsPromise().

We have the same issue here, the same concerns, be able to:

- get the result of a promise or at least have a way to attach a resolve and reject callbacks when calling `JSObjectCallAsFunction`
- have a JSValueIsPromise helper method
