CODE:

var userNumbers=[1,6,41,8,24,4];

console.log(userNumbers[2])  //display element as index 2

console.log(userNumbers[3])  //display element as index 3

6)

we need to give proper closing and ending tags like

<head></head>

<body></body>

<title></title>

<br />

7)

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">

<title>Learning HTML</title>
</head>
<body>
   <center>This page uses deprecated HTML.</center> <!-- this is deprecated -->
</body>
</html>

line break is used to break the line and white space is used to give space between words as we required by manually if we type space it treats all the spaces as single space.

<!DOCTYPE html>
<html>
<head>
   <title></title>
</head>
<body>
<p>first line
&nbsp;second &nbsp;&nbsp;&nbsp; para </p><br/>
<p>third npara</p>

<table>

<tr>

<th>Head 1 </th>

<th>Head 2</th>

<th> Head 3</th>

</tr>

<tr>

<td>Item 1</td>

<td>Item 2 </td>

<td>Item 3</td>

</tr>

</table>
</body>
</html>

9)

var names = [];

names[0] = "Sue";

names[1] = "Bob";

names[2] = "Jeff";

console.log(names[0] + names[1]);       //print sue and bob
