javascript - How to access the functions and objects requireJS module -

-

i'm working on scripts site uses requirejs , weird syntax i've never seen before. 

define("app/models/usermodel", ["backbone", "lang/lang"], function (e, t) {     var n = e.model.extend({         defaults: {             item: "",             these: "",             arent: "",             important: "en",             relationship: 0,             _position: {                 c: 0,                 r: 0             }         },         haspermission: function (e) {             return this.get("permission") >= e         },         gettotalpoints: function () {             return this.get("somestuff")         }     });

i've used require(["app/models/usermodel"]) load module , require("app/models/usermodel").default try , load object , same method try , use functions comes saying don't exist. i've been able access functions in model same way of others doesn't work.

aside wondering if var n = e.model.extend has it. can't understand function of is.

the structure required asynchronous module loading work. requirejs module constructed within function called define; function supposed return public interface of module. in case, need like:

define("app/models/usermodel", ["backbone", "lang/lang"], function (backbone, lang) {     var mymodel = backbone.model.extend({         defaults: {             item: "",             these: "",             arent: "",             important: "en",             relationship: 0,             _position: {                 c: 0,                 r: 0             }         },         haspermission: function (e) {             return this.get("permission") >= e         },         gettotalpoints: function () {             return this.get("somestuff")         }     });      // return created model object     // accessible require("app/models/usermodel").default_     return {         default_: mymodel     } });

(beware not familiar backbone, though). also, guess module using minified , beautified, because variable names 1 letter long, , not mnemonic? also, default keyword, use within switch statements, , not valid variable name @ all.
