how to log string variable prototype properties in console?

Question

I tried below code

var carname = "Volvo XC60";
console.dir(carname);

This gives nothing but the value. I want to list all prototype functions associated with this variable. This one also is not working.

console.dir(carname.prototype);

Any idea what am I doing wrong?

If you just want to see what methods are available, use the MDN documentation. — Andy

What prototype functions do you want to see? For native try this:

console.log(new String('carname'));

console.dir(carname); worked! console.log() doesnt log prototypes.

@Shreejibawa my Google Chrome Dev Tools thinks different

@Shreejibawa: Only because primitive strings are no objects, and don't have prototypes.

In Firefox, these function behave quite differently: log only prints out a toString representation, whereas dir prints out a navigable tree. In Chrome, log already prints out a tree -- most of the time. However, Chrome's log still stringifies certain classes of objects, even if they have properties.
