Why can"t  window.location.reload  be called back? 
        // 
        function fn01 (fn){
            fn && fn();
        };
        function callBackFn(){
            console.log("");
        };
        // 
        fn01(callBackFn); //
        fn01(window.print); //
        fn01(window.location.reload); //
        //

 I know that you can wrap  location.reload  with an anonymous function, and then you can implement a callback 
. I wonder why it can"t be called back. 
 Thank you for your help from the old driver, and thank you for answering

 this 
fn01(window.location.reload.bind(location));
