JavaScript Number Pattern 17

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<=10; i+=2)
{
 for(j=i; j<=10; j+=2)
  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;: Declare two variables i and j to be used as loop counters.
Outer loop begins: for(i=1; i<=10; i+=2): This loop iterates through odd numbers from 1 to 10 with a step of 2. So, i takes on the values 1, 3, 5, 7, and 9 during each iteration.
Inner loop begins: for(j=i; j<=10; j+=2): This loop iterates through odd numbers starting from the current value of i up to 10 with a step of 2. The value of j takes on the values of i, i+2 , i+4, and so on, up to 10.
Inside the inner loop: document.write(j);: The value of j is written to the document. This means that during each iteration of the inner loop, an odd number (starting from i and increasing by 2) is written to the document.
After the inner loop completes: document.write("<br>");: A line break (<br>) is written to the document. This creates a new line after each set of odd numbers written by the inner loop.
The outer loop repeats its iterations until i exceeds 10.

💯 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.
