Is multiple inheritance possible in javascript? [duplicate]

Question

I have a situation here. I have two modules(nothing but javascript function) defined like this:

Module1:

define(function(){
    function A() {
        var that = this;
        that.data = 1
        // ..
    }
    return A; 
});

Module2:

define(function(){   
    function B() {
        var that = this;
        that.data = 1;
        // ...
    }
    return B; 
});

How to inhert both modules inside other module?

Answer 1

1) In js everything is just an object.

2) Javascript inheritance uses prototype inheritance and not classic inheritance.

JavaScript doesn't support multiple inheritance. To have both of them inside the same class try to use mixins that are better anyhow:

function extend(destination, source) {
  for (var k in source) {
    if (source.hasOwnProperty(k)) {
      destination[k] = source[k];
    }
 }
 return destination; 
 }

 var C = Object.create(null);
 extend(C.prototype,A);
 extend(C.prototype,B);
