JavaScript Number Pattern 48

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, res = 1;
for(i=1; i<=5; i++)
{
 if(i == 1)
  res = i;
 else
  res = res * 11;
 document.write(res);
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

🧠 How the Program Works

Let's break down the logic behind the code:

var i, res = 1;: This line declares two variables, i and res, and initializes res with the value 1. i is used as a loop counter, and res will store intermediate results.
for(i=1; i<=5; i++): This line starts a for loop that will execute a block of code multiple times, incrementing the value of i from 1 up to 5 (inclusive). The loop will repeat five times.
Inside the loop:
1. if(i == 1): This condition checks if the current value of i is equal to 1.
  - If i is 1, the program sets res to 1.
  - If i is not 1, the program goes to the else block.
2. else: This block is executed when the condition i == 1 is false, which means i is not equal to 1.
  - Inside the else block, the program multiplies the current value of res by 11 and assigns the result back to res. This effectively generates a sequence of numbers where each new number is the previous number multiplied by 11.
3. document.write(res);: This line writes the value of res to the HTML document. Since it's inside the loop, it will output the current value of res in each iteration of the loop.
4. document.write("<br>");: This line writes an HTML line break <br> to the document, creating a new line after each value of res that is written.
The loop continues to execute, incrementing the value of i by 1 in each iteration, and performing the steps outlined above until i reaches 5.
Once the loop completes, the program ends.

💯 Tips for Enhancement:
