Difference between the implementation of var in Javascript and C#

Question

I would like to ask a theoretical question. If I have, for example, the following C# code in Page_load:

cars = new carsModel.carsEntities();

var mftQuery =          


        

Answer 1

The only thing they have in common is that they are used to declare local variables.

The C# equivalent of JS var is dynamic. But since most C# users prefer static typing it is usually only used in interop scenarios of some kind(with COM or a dynamically typed language).

C# var still uses static typing, but with an inferred type. Since JS only supports dynamic typing, there is no equivalent.

In this context explicit static typing isn't possible, since new {mft.CompanyID, mft.CompanyName} creates an anonymous type, so implicit static typing with var is used.
