JavaScript Number Pattern 10

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

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j;
for(i=5; i>=1; i--)
{
 for(j=5; 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:

🧠 How the Program Works

Let's break down the logic behind the code:

var i, j;: This line declares two variables i and j without initializing them.
for(i=5; i>=1; i--) {: This is the outer loop. It initializes i to 5, and the loop continues as long as i is greater than or equal to 1. After each iteration, i is decremented by 1.
Inside the outer loop, we encounter the inner loop:
- for(j=5; j>=i; j--) {: This is the inner loop. It initializes j to 5, and the loop continues as long as j is greater than or equal to the current value of i. After each iteration, j is decremented by 1.
document.write(i);: Inside the inner loop, this line writes the current value of i to the document. Since the inner loop is executed multiple times based on the value of j, it prints the value of i multiple times in a row.
After the inner loop completes, the program goes back to the outer loop and executes the rest of its content.
document.write("<br>");: This line writes a line break (<br>) to the document, causing the next output to appear on a new line.
The outer loop continues its iterations until i becomes less than 1, at which point the loop terminates.

💯 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.
