Simple for loop

for (var key in j2) { j1[key] = j2[key]; }

yes, you can implement your own function of inheritance :

function inherits(base, extension)
            {
                for (var property in base)
                {
                    try
                    {
                        extension[property] = base[property];
                    }
                    catch(warning)
                    {
                    }
                }
            };

then

inherits(j2,j1)
console.log(j1)
// Object {name: "Varun", age: 24, code: "NodeJS", alter: "C++"}
