Question

Following is the code:

var myVar = {
    test:function(){
       alert('hello');        
    },
    myinternalObj: {
        internalTest: myVar.test
    }
};

Why in javascript I’m unable to assign myVar.test to internalTest?

Answer 1

myVar.test is evaluated before the assignment (of the object literal) to myVar and thus myVar is undefined and accessing a property on undefined or null results in an error.
