- the word "is" is not a JavaScript operator
- the parentheses following an "if" should contain a comparison expression
- conditional code goes between the braces that come after the conditional expression
- there should not be a semicolon between an "if" condition and the brace of the code block

Second, JavaScript's alert method does not return a boolean but returns no value, so it does not make sense to call the method inside else if parentheses.
By judging your code, maybe you want to do this?
var isAdmin = true;
var isStudent = false;
if (isAdmin === true) { // or just if(isAdmin)
alert("Welcome administrator")
} else {
// code for not an admin
}
