Why does a primitive variable act like an Object? [duplicate]

Answer 1

For both,

var num1 = new Number(34); 
num2 = 34;

You are assigning "Number" type values to both num1 and num2 variables. So it calls the prototype, which attached to the "Number".

But calling 34.sayMyNumber has syntax error and its an illegal statement.
