Why is `size` just a function? #1226

Closed j-f1 closed 2 years ago

j-f1 commented 2 years ago

Both ByteLengthQueuingStrategy and CountQueuingStrategy are defined as having a readonly attribute Function size. However, the definition for QueuingStrategy has a specific type for this field: QueuingStrategySize. Is there a reason these two interfaces do not use the more specific type?

This is due to how Web IDL works. The type of attributes don't really matter, and it's easier to create a Function in spec text. Whereas the types of dictionary members have normative impacts on how inputs are processed and called.

Hope this helps!
