Hello, I would like to know in this video when we have:
name = prompt ("What's your name?");
if (name) {
...
}
which state does name transit to if no name is provided in the prompt: null or undefined?
I guess it should go to undefined since it was not assigned any value to it. Is it correct?

var username
username = prompt("What is your name?")
username
You will see that console will write "undefined" at first, but after the promt it will give the values of username as "".
