1. Variable Functions

Script function show () {alert ("first... ");} Function show (str) {alert (" second ");} function show (a, B) {alert (" third... "); Alert (a +": "+ B);} script 
  
    
 Script show (); // When called, the previous show will be washed out // undefined: undefined show (111); // after the call, the previous one will be washed out. // 11: undefined show ("a", "B"); // after the call, the previous one will be washed out. //: B show (,); // script

In summary, functions in Javascript do not have heavy loads. All of them must be configured. Although a function declares several variables during definition, it can be passed in to any variable during the call. Each function contains a default array of arguments, which stores all the arguments passed in during this call.
