Total beginner bere, could somebody explain why this if statement isnt working?

Question

var name = prompt("Please tell me your name?");

if (name != null) {
alert("Hello " + name + "! How are you?");
} else {
alert("You didn\'t enter a name!");
}

How would I check if the prompt string is 'null/empty'?

Thanks!
