when i run the program the browser tell me moy is NaN yet I took care to use .map(Number) to convert the array into a number . I need some help please.
var score = [];
var i = 0;
var choice = 0;
while(choice != null){
i++;
score.push(prompt("put the score number "+i));
score = score.map(Number);
choice = prompt("to continue click on ok to cancel click on cancel");
}
var sum = 0,moy;
for(a=0;a<=i;a++) {
sum = sum+score[a];
moy = sum/i;
}
document.write("you put "+i+" score(s) <br>and the average is"+moy);
