In this task you are asked to use conditional if else statements. Basic structure of a if else statement looks something like this. 

if ( ) {

}

In the parentheses, evaluates a boolean expression so that if it evaluates to true the code between the curly braces run. So for this task, in the parentheses check if isAdmin true or not. If true, type the code between the braces that will run.

Hope this helps!

To follow up on Vrund's answer:

if ( [expression] ) {
  //Code if expression is true here
} else {
  //Code if expression is false here
}

You can also chain together if else statements by simply starting another if after the else

else if ( [Other expression ){
  //Code if [Other expression] is true here
}
