If value is null or undefined, create and return a new object with no properties other than internal properties exactly as if the object constructor had been called on that same value (15.2.2.1). 2. Return ToObject (value), whose rules are: undefined generate a runtime error null generate a runtime error boolean create a new Boolean object whose default value is the value of the boolean. number Create a new Number object whose default value is the value of the number. string Create a new String object whose default value is the value of the string. object Return the input argument (no conversion).
