Solution 1

C#

string myString;
// or
string myString = "value";

Javascript:

JavaScript

var myString;
//or
var MyString="value";

In C# you must specify the type, but in Javascript, the act of assigning a value defines a variable's type. You can also specify the type explicitly if you want.

in C# you don't need to specify the type either when you are using C# 3.0 or higher during development. You can simply use "var" and the compiler which get you the right type..

Many highly experienced developers including myself would discourage the use of var. Explicitly defining the type both in the variable declaration and initialization provides a second level of type validation, especially in the case of the example John gives using string.

I've been coding a LONG time. I don't believe in "typeless" languages, and would never avoid specifying the desired type. For work, I code in VB.Net (but only because I'm forced to) and I refuse to let the compiler assume what I really want to do. I even scope all of my If statements with parenthesis, which drives my co-workers completely insane.

Finally, someone else who annoys the hell out of coworkers with these behaviors. I do the same thing.

I personally agree with you both (I indeed didn't mention that), but personal preferences and thoughts on best practises in coding is not what he asked :), so the general statement that it's not possible is incorrect, but both of you are completely correct that you should avoid using it.

I apologize if my comment was taken as a slight against your answer. It was not intended as that. I was just offering my personal position on the use of var for the OP the chew on. Cheers.

For my comments goes the same :). I guess the problem with these kind of questions are the kind of correct answers you have. You have the Microsoft-correct answers, but also the Community-correct answers. Which answer is the one the author wants? ;) But now we have given Shashikant@Jalgaon both, so he can pick his prefered one.
