JavaScript Number Pattern 11

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

example.html
Copied
Copy To Clipboard
<!DOCTYPE html>
<html>
<body>

<script>
var i, j;
for(i=5; i>=1; i--)
{
 for(j=1; j<=i; j++)
  document.write(i);
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

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

Output
55555
4444
333
22
1

🧠 How the Program Works

Let's break down the logic behind the code:

  1. <script> tag: This indicates the start of a JavaScript code block embedded in an HTML document.
  2. var i, j;: Declares two variables i and j that will be used as loop counters in the following loops.
  3. for(i=5; i>=1; i--): This is the outer loop that initializes i to 5, runs as long as i is greater than or equal to 1, and decrements i by 1 in each iteration. This loop controls the number of rows in the pattern.
  4. Inner Loop:
    • for(j=1; j<=i; j++): This is the inner loop that initializes j to 1, runs as long as j is less than or equal to the current value of i, and increments j by 1 in each iteration. This loop controls the number of times the current value of i should be printed in the same row.
    • document.write(i);: Inside the inner loop, this line writes the current value of i to the document. Since the inner loop runs i times, this will print the value of i that many times on the same line.
  5. document.write("<br>");: After the inner loop completes, this line writes an HTML line break <br> to the document. This causes the output to move to the next line, creating the pattern effect.
  6. After both loops complete for a given value of i, the outer loop decrements i by 1, and the process repeats until i becomes less than 1, which ends the pattern generation.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.

✔ Conclusion:
