Lately I read that for every primitive data type, a wrapper object is created. It is this wrapper object what makes it possible to use methods with that data, and that makes sense.
I also read that functions are objects. I found out that I can visualize the function-as-an-object through console.dir()
.
However, when I apply console.dir()
to a primitive data type, I get the value of the variable. But I was expecting to get an object, just as with functions. Is this because they are different cases? How can I access the wrapper object of a primitive data type?

try __proto__
property.
eg var a = ‘something’;
console.log(a.__proto__
);
this is a deprecated feature though, the better way would be to use Object.getPrototypeOf(<primitive here>)
.
