I feel proponents of any programming language put a lot of spin around what isolated aspects it is good for, but fail to illustrate what a programmer in even one target domain gains from using it.
Are there programming language implementations unlike what is described above, that you feel back up their marketing?
Object-oriented is a design pattern that the language can facilitate. Just because a language supports “is a” doesn’t mean “has a” does not exist. There are a lot of design patterns. Use the best language and design patterns for your team.
