How can I change the content of the paragraph tag from HTML by JavaScript without using document.write? Why is it not showing when I view it in a browser? please help me learn this. Thanks
var grades = [45, 32, 66];
var sum = 0;
if (grades.length>0){
for (index=0 ; index<grades.length; index++)
sum += grades[index];
console.log(sum);
document.getElementById('here').innerHTML = sum/grades.length;
}
else
document.getElementById('here').innerHTML = "Empty Array";<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Array average with zero</title>
<script src="js/arrays2.js"></script>
</head>
<body>
<p id="here">See Average Here</p>
