I don't understand this challenge in Javascript.

Question

I don't get why the output of the following code in JavaScript is 333. Could anyone explain it please?

for(var i=0; i<3;i++){
setTimeout(function(){
document.write(i);}
,200);
}

Answer 1

maybe Timeout capture last value of i, and execute 3 times, because the "for" is executed before of timeout function
