The format is as follows ：

}

Invocation time fn();

 function fn() {

        }

The format is as follows ：

var Variable name = function(){

}

Different from defining variables , What is stored in the definition variable is the variable , What is stored in this is the function .

It's also called fun(), Parameters can also be passed in parentheses .

 var fun = function(arr, arr1) {
            // console.log(arguments[1]);
            console.log(arr);
            console.log(arr1);
        }
