I have two simple questions for you about boolean values in Javascript.
When will browser show alert message:

if (a-b) alert(“it’s true!”);

And another one

What will be printed as result of running this script:

for (var n=10; n; n– )
{
document.write (n + “,”);
}

The answer for both questions relies on the same principle of what JavaScript engine will evaluate as true and what as false.

Another great interview question.
Will the following code compile and if yes what will be the result of it ?
static void Main(string[] args)
{
int[] array = new[] {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

Func<int, int> func = i => {
Console.Write(array[i]);
return i;
};

var result = array.Where(e => e <= func(2)).ToArray ();
}
* There is a second part for this question, but only after you answer the first one.
