We were given code in puter science which we were supposed to look at and explain and then we're supposed to add to it.

This is the code:

<!DOCTYPE html>
<html>
<head>
<title>Example Website</title>
</head>
<body>
<p id="demo"></p>

<script>

var array = ["example1","example2","example3"];

document.getElementById("demo").innerHTML = array[0]

</script>

</body>
</html>

What he wanted us to do now was make it print the array in separate lines with bullet points instead of just printing the first thing within the array which is 'example1'.

He said to use any resources you can from the internet to find out how and to try and remember the information found and then explain it during class.

Well, you can use .join(), <ul> and <li>s. The .join() helps in converting the array into a string joined by the parameter given in the .join().

<p id="demo"></p>
<script>
  var array = ["example1","example2","example3"];
  document.getElementById("demo").innerHTML = '<ul><li>' + array.join("</li><li>"); + '</li></ul>';
</script>

The above displays like:

A bullet point list in HTML looks like this:

<ul>
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
</ul>

So to print something like that you'll want to follow these steps:

  1. Print out the opening <ul> tag
  2. Loop through the array and print each array element surrounded by <li> tags
  3. Print out the closing </ul> tag

var array = ['example1', 'example2', 'example3'];

var s = '<ul>';

for (var i = 0; i < array.length; i++) {
  s += '<li>' + array[i] + '</li>';
}

s += '</ul>'

document.getElementById("demo").innerHTML = s;
<div id="demo"></div>
