What is the difference between ‘abstract new (…args: any[]) => T’ and ‘new (…args: any[]) => T’ as a type?

Accepted Answer

The difference lies in the acceptance of abstract classes. The 'abstract new' constructor type allows abstract classes, while the 'new' constructor type only accepts classes that can be directly instantiated.
