IE alerts with 'undefined', Chrome fine

If I use IE, it prompts with a prefilled 'undefined', which must be overwritten with the value you want to enter. In Chrome, it does alert with an empty alert box, as it should.

How to make IE behave like Chrome, and the alert box to have no initial value?

I tried with initializing the variable to an empty string or null, but doesn't help. var visitorName = ""; console.log(typeof visitorName); visitorName = prompt("What is your name?");

Found the answer myself, for IE, the code must be

var visitorName = prompt("What is your name?","");
