JavaScript Number Pattern 22

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=1; i<=9; i+=2)
{
 for(j=1; j<=i; j++)
  document.write(j);
 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 declares two variables, i and j, without initializing them.
for(i=1; i<=9; i+=2): This is the outer loop. It initializes i to 1, and the loop will continue as long as i is less than or equal to 9. In each iteration, i is incremented by 2 (since we want odd numbers).
Inside the outer loop:
- for(j=1; j<=i; j++): This is the inner loop. It initializes j to 1, and the loop will continue as long as j is less than or equal to the current value of i. In each iteration of the inner loop, j is incremented by 1.
- document.write(j);: This writes the value of j to the document. This means that the numbers from 1 to the current value of i will be written to the document in each iteration of the inner loop.
document.write("<br>");: After each iteration of the inner loop, a line break (<br>) is written to the document. This creates a new line, separating the output of each iteration.

💯 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.
