Var?

Why would you use var instead of double for example. Doesn't var make the code more diffcult to read?

Using "var" just lets the compiler determine the type for you. In many cases, a variable is being declared and initialized at the same time, so the type is obvious to both the compiler and the reader from what is being assigned to it. I personally think the code can be easier to read at those times.

But if the type isn't clear at first glance, even if the compiler can determine it, I think you have a strong case for using a explicit type declaration for readability.

Happy coding!
