How do I make an alert() that prints out the value of a variabile?

Question

I'm trying to make an alert, that prints the value of a variabile, here is my attempt.

var username = prompt("I'm LaunchBot, what's your name?");   
var print = alert() ;

Please read the [docs](https://developer.mozilla.org/en-US/docs/Web/API/Window/alert) and research before asking. — Sebastian Simon, May 18 '18 at 12:52

Per my answer to the above possible duplicate question: alert("The variable named x1 has value: " + x1); — JosephDoggie, Jan 07 '20 at 20:25

alert() is a function. It take a parameter between the parenthesis. So just insert your variable username between them:

var username = prompt("I'm LaunchBot, what's your name?");   
alert(username) ;

As suggested in the comment alert() doesn't return anything so do not add a variable assignment before.

Also, it doesn’t return anything, so `var print` is superfluous. – Sebastian Simon May 18 '18 at 12:52
