Sets a property on an object using a JSValueRef as the property key.

Parameter ctx: The execution context to use.

Parameter object: The JSObject whose property you want to set.

Parameter propertyKey: A JSValueRef containing the property key to use when looking up the property.

Parameter value: A JSValueRef to use as the property’s value.

Parameter attributes: A logically ORed set of JSPropertyAttributes to give to the property.

Parameter exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

This function is the same as performing “object[propertyKey] = value” from JavaScript.
