How can I write modular code in Julia?

To write modular code in Julia, you can use modules to encapsulate related functions and types. This helps in organizing your code.

Can you show me an example of a simple module?

Sure! Here's a simple example:

module MyMath
    export add, subtract
    function add(x, y)
        return x + y
    end
    function subtract(x, y)
        return x - y
    end
end

How do I use this module in my code?

You can use the module by importing it with using MyMath or import MyMath. Then you can call the functions like this:

using MyMath
result = add(5, 3)

What are the benefits of using modules?

Modules help in organizing code, avoiding name clashes, and improving code reusability. They also make it easier to maintain and test your code.
