Can someone tell me why this code outputs 6

Question

var x=3;
var i=0;
while(i<3){
x+=1;
i+=1;
};
document.write(x);

Answer 1

At the beginning x = 3. You go through the loop 3 times and you add 1 to x each times. So finally you have done x = x + 3 = 3 + 3 = 6...

Does that help or should I explain another way?
