Answer 2

Answer:

Correct option is 7 undefined

Explanation:

var car={type:"maruthi",model:"zen",color:"white"};

alert(car.price);

Undefined is the sort of variable that hasn't been assigned a value. If the variable being evaluated does not have an assigned value, the method or expression returns undefined. If no value is returned, a function returns undefined.

variable is undefined:

So the correct way to test undefined variable or property is using the typeof operator, like this: if(typeof myVar === 'undefined') .
