How to implement simple router functions in JS

The example in this article describes how to implement simple router functions in JS. Share it with everyone for your reference. The specific implementation method is as follows:

var wawa = {};
wawa.Router = function(){
  function Router(){
  }
  Router.prototype.setup = function(routemap, defaultFunc){
    var that = this, rule, func;
    this.routemap = [];
    this.defaultFunc = defaultFunc;
    for (var rule in routemap) {
      if (!routemap.hasOwnProperty(rule)) continue;
      that.routemap.push({
        rule: new RegExp(rule, 'i'),
        func: routemap[rule]
      });       
    }
  };
  Router.prototype.start = function(){
    console.log(window.location.hash);
    var hash = location.hash, route, matchResult;
    for (var routeIndex in this.routemap){
      route = this.routemap[routeIndex];
      matchResult = hash.match(route.rule);
      if (matchResult){
        route.func.apply(window, matchResult.slice(1));
        return; 
      }
    }
    this.defaultFunc();
  };
  return Router;
}();
var router = new wawa.Router();
router.setup({
  '#/list/(.*)/(.*)': function(cate, id){
      console.log('list', cate, id);
    },
  '#/show/(.*)': function(id){
      console.log('show', id); 
    }
}, function(){
  console.log('default router');
});
router.start();
