JavaScript Number Pattern 26

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<=5; i++)
{
 for(j=5; j>=1; j--)
 {
  if(i == j)
   document.write("*");
  else
   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, which will be used as loop counters in the subsequent loops.
for(i=1; i<=5; i++): This is the outer loop that iterates over the values of i from 1 to 5 (inclusive).
Inside the outer loop, there is another nested loop:
- for(j=5; j>=1; j--): This is the inner loop that iterates over the values of j from 5 to 1 (inclusive).
Inside the nested loop, there's an if condition:
- if(i == j): This checks if the current values of i and j are equal.
If i is equal to j, it writes an asterisk (*) to the document using document.write("*");.
If i is not equal to j, it writes the value of j to the document using document.write(j);.
After the nested loop completes, the program writes a line break (<br>) to the document using document.write("<br>");. This moves the output to the next line.
The outer loop continues to the next iteration until i reaches 5.

💯 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.
