So else doesn't have a () or condition ever?

Question

So else doesn't have a () or condition ever?
Would you ever see this
else () {
alert("You win!");
}
Also.... on the alerts and window messages which is correct to do with the ;
if else (){
alert ("tacos");                           
}
if else (){
alert("tacos") 
}

It never has a condition or a parenthesis, that is correct. 
The point of the else statement is that it automatically runs if the if/else if statements above it does not. Also as far as semicolons go your first example:
JavaScript 
if else (/* Condition goes here */){ 
    alert("tacos");
}

Is correct. The one thing about semicolons and if/else if statements that you have to be very careful about is that you should never place a semicolon after the parenthesis containing its conditions. If you do then the statement will be terminated prematurely. And the code you placed in the body of the if/else if will be executed regardless of whether the conditions evaluated to true or not.
