NewPromiseCapability section has to be clear about GetCapabilitiesExecutor call

[thefourtheye]

As it is, NewPromiseCapability section says

Let executor be a new built-in function object as defined in GetCapabilitiesExecutor Functions

but the GetCapabilitiesExecutor Functions is defined as

When a GetCapabilitiesExecutor function F is called with arguments resolve and reject the following steps are taken:

So, it is not very clear what the functions passed to GetCapabilitiesExecutor from NewPromiseCapability.

Can someone please explain?

The purpose of GetCapabilitiesExecutor is to extract the resolve and reject functions from constructing a new promise and pack them into a PromiseCapability record. Think of it like this:

function makeGetCapabilitiesExecutor() {
    return function F(resolve, reject) {
        F._Capabilities.resolve = resolve;
        F._Capabilities.reject = reject;
    };
}
