# Chapter 6, Inheritance

Lets solve the following exercise:

## Exercises

1. Multiple inheritance by mixing into the prototype, for example:
```        var my = objectMulti(obj, another_obj, a_third, {
});
A possible solution:
function objectMulti() {
var Constr, i, prop, mixme;

// constructor that sets own properties
var Constr = function (props) {
for (var prop in props) {
this[prop] = props[prop];
}
};

// mix into the prototype
for (var i = 0; i < arguments.length - 1; i++) {
var mixme = arguments[i];
for (var prop in mixme) {
Constr.prototype[prop] = mixme[prop];
}
}

return new Constr(arguments[arguments.length - 1]);
}
```

Testing:

` > var obj_a = {a: 1}; > var obj_b = {a: 2, b: 2}; > var obj_c = {c: 3}; > var my = objectMulti(obj_a, obj_b, ...`
