Debugging a program involves fixing errors to make a program work properly. Common errors include missing quotation marks, missing semicolons at the end of statements, variables without names, and spelling mistakes. The document provides examples of code with various bugs like typing errors, missing elements, and logical errors to demonstrate issues that may occur and need to be fixed through debugging.

1. Debugging a program
Debugging a program is when we fix any
mistakes to make the program work.We should
look for common errors such as -
1. no quotation marks “”
2.if a sentence has no ; at the end
3. variables with no name
4.spelling mistakes

2. Example 1
<script type=text/javascript>
var name=promtp (enter your name)
document.wrote (NAME)
</script>

3. Example 2
<script type=”text/javascript>
var num=promtp (enter a number)
if (num >>10){
document.wrote (thats a small number)
</script>

4. Example 3
<script type=”text/javascript>
var name=prompt (enter your name)
document.write (NAME.substring (0,s))
</script>

5. Example 5
<script type=”text/javascript>
var number= prompt.number (enter a number to
get it's square root)
number=parseint(number)
var math= number*number1
alert (NUMBER)
</script>

6. Example 6
<script type=”text/javascript>
var number= prompt.number (enter a number to
get it's square root)
number=parseint(number)
var math= number*number1
alert (NUMBER)
</script>

7. Example 7
<script type=”text/javascript>
var word= prompt(enter a fruit)
if (word==banana){
alert (yes){
alert (no)
