JavaScript Number Pattern 6

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=i; j<=5; 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:

Output

🧠 How the Program Works

Let's break down the logic behind the code:

Variable Declaration: Two variables i and j are declared using the var keyword.
Outer Loop (for Loop):
- for(i=5; i>=1; i--): The outer loop initializes i with the value 5. It will continue as long as i is greater than or equal to 1. After each iteration, i is decremented by 1.
Inner Loop (for Loop):
- for(j=i; j<=5; j++): The inner loop initializes j with the value of i. It will continue as long as j is less than or equal to 5. After each iteration, j is incremented by 1.
Inside Inner Loop (document.write(j)):
- Here, within the inner loop, the value of j is printed using the document.write() method. This method appends the value of j to the document's content.
Line Break (document.write("<br>")):
- After printing the numbers for the current value of i, a line break <br> is added using document.write(). This creates a new line in the output, separating each set of numbers.
Repeat Inner Loop and Line Break: Steps 3, 4, and 5 are repeated as long as the conditions of the inner loop are satisfied.
Repeat Outer Loop: Once the inner loop completes for the current value of i, the outer loop continues its iterations with the next value of i (decremented by 1). The process from steps 3 to 6 is repeated for each value of i in the range from 5 to 1.

💯 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.
