If Statement (C# and JavaScript Cross Reference Guide)

By Mike Prestwood

C# versus JavaScript: A side by side comparison between C# and JavaScript.

Statements

Common statements such as if statements, loops, etc.

If Statement

[Other Languages]

C#: if..else if..else

Use () around evaluation with no "then".

Syntax Example:

Boolean x = true;



if (x)
{
  MessageBox.Show("hello");
}
else if (x==false)
{
  MessageBox.Show("goodbye");
}

else

  MessageBox.Show("what?");
}

JavaScript: if..else if..else

Same as C/C++ but, as usual, the semicolons are optional.

Syntax Example:

var x = 8;

if (x == 10) {
 document.write("x is 10.");
} else if (x < 10) {
 document.write("x is less than 10.");  
} else {
 document.write("x must be greater than 10."); 
}
