Simplify this If statement so it doesn't duplicate code – Javascript

I have an If statement that runs within a \’for\’ loop to create markers for a Google map. Basically if a tick box is not ticked it runs the code all displays all markers, but if a checkbox is ticked then it checks for a 2nd parameter and only runs the code for the items that match this condition.

The code I have below works fine, but it means I have to use the same code in both parts of the if statement. Apart from building it into a function if there a better way of structuring the If statement to achieve this?

if(!FriendlyChecked){

    //Code here

} else if(FriendlyChecked && Friendly == \"Yes\"){

    //Same code here

}
