multiple Inheritance in JS [duplicate]

Question

There javascript class, if he can 'inherit' a few objects - that is, to know their methods

var A = function  (a,c){};

var N = {  
     properties1: function(){};
};

var M1 = {
     properties2: function(){};
};
var M2 = {
     properties3: function(){};
};

How to do that would 'A' , knew (the heir) of 'N' and 'M1' , 'M2' ...'M10' ... ?

A.prototype = N;
A.prototype = M1;
A.prototype = M2;

It does not work :( How to implement such an event structure in javascript

Can it be like that circumvent or emulate?If you need a structure described above ? — R__

I wonder why you even expect assigning to A.prototyep multiple times to work. If I have this code: var a = 1; a = 2; a = 3;, then in the end, a will have the value 3, not 1, 2, 3 (somehow). — Felix Kling

Javascript has prototypical model/inheritance. Please use it and avoid writing Java/C++ in Javascript. It's a different model.

EDIT:

In my opinnion if you need such a thing - you're doing it wrong :). And I very much recommend to read this SO answer about prototypes.

How does this answer the question?

A.prototype = N; A.prototype = M1 === replaced by === A.prototype.properties1 = N.properties1; A.prototype.properties2 = M1.properties2
