I am coming from Matlab and Python background and I have recently started considering Julia seriously for software development. My main question is why Julia is not designed as OOP like python? As far as I can see OOP is not against speed and multiple-dispatch but in contrast it allows a very clean…

I understand completely that this is not a perfect solution, or a one-to-one comparison, but maybe an example may help: You can define an interface inside a module, which clearly define the methods that should be defined for a certain type: module Animal abstract type AbstractAnimal end name(::A…

[image] haghighat: Also, I donot get the idea of multiple dispatch: even in OOP when we write object.function(params) it is first converted to function(object, params) and then it runs. So I guess the idea is the same … The same function can have different signatures … To be absolutely precis…

Thank you so much. I haven’t though this way. You are right, this may work, but it would be a little awkward in big projects I guess.

yes and no! I think you are right about Python, one cannot do this in Python because once a function is redefined it replaces the previous definition. So the only possibility to get different responses is to check the argument value, via default arguments, which will take time and will not compile.…

Overloading is definitely similar to multiple dispatch, but they’re not quite the same. See this long discussion: [image] Claim (false): Julia isn't multiple dispatch but overloading General Usage I heard a rumour that Julia’s multiple dispatch is “fake news”, in reality …

I agree with you after reading the thread you mentioned. And the difference is that overloading is just at the compile time and it may produce a lot of version of code, which may not be used. In multiple dispatch this is decided based on JIT compiling. So, the compiler may produce just a single ve…

Thanks a lot for the response. I completely understand what you mean. What I was trying to say was that OOP function-class structure can be included in multiple-dispatch without any issues. The bottom line is that: if a function is included inside a class, it means it is going to be used by a l…

[image] haghighat: So this surprises me why OOP is removed in Julia. OOP (in the traditional single-dispatch sense), was never removed from Julia, because it was never added to Julia. Note, in Julia everything is an object, in some sense, unlike in most languages, such as Python and C++. Peo…

As stated many times by Alan Kay, who created the term OOP, there is a common confusion between OOP and Abstract Data Types. See his answers below, where he just scratches the surface on what “real OOP” is about: [image] What thought process would lead one to invent object-oriented programm…

Why there is no OOP (object oriented programming) in Julia?

Overloading is definitely similar to multiple dispatch, but they’re not quite the same. See this long discussion:
