why does not it work // почему код не выводит 6000?

Question

function myAlert() {
alert("Hi");
}
setInterval(myAlert, 3000);

clearInterval(myAlert, 6000);

Answer 1

function myAlert(){ alert("Hi"); }
var i = setInterval(myAlert, 3000);

setTimeout(function(){ clearInterval(i) },6000);

Answer 2

because you have to assign setInterval to a variable then clear it I think
