JavaScript Number Pattern 19

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 +" ");
 for(j=1; j<i; j++)
  document.write("5 ");
 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:

Declare variables i and j without assigning any initial values.
Enter a for loop that initializes i to 5 and continues looping as long as i is greater than or equal to 1. The loop decrements i by 1 in each iteration.
Inside the outer loop, there is another nested for loop that initializes j to the current value of i and continues looping as long as j is less than or equal to 5. This loop prints the values of j followed by a space using document.write(j + " ").
After the nested loop, there is a second nested for loop that initializes j to 1 and continues looping as long as j is less than the current value of i. This loop prints the number 5 followed by a space using document.write("5 ").
Finally, after both nested loops, document.write("<br>") is used to add a line break, creating a new line in the output.
The outer loop continues to iterate, decreasing the value of i by 1 in each iteration, and steps 3-5 are repeated for each value of i.

💯 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.
