When ‘new’ is used, an object is created that has other than the usual default Object prototype object.
The ‘create’ operator is in some sense simpler than the ‘new’ operator, but each can be defined in terms of the other. According to Wikipedia, syntactic sugar “is syntax designed to make things easier to read or to express, while alternative ways of expressing them exist”.
I think ‘create’ is simpler to use and understand than ‘new’, and so I don’t regard it as syntactic sugar for the creation creation of objects. The same Wikipedia term also suggests the term syntactic saccharin for gratuitous syntax which does not actually make programming easier. I consider ‘new’ to be syntactic saccharin.
