JavaScript Number Pattern 52

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j, k, m;
for(i=1; i<=5; i++)
{
 m = i;
 for(j=1; j<=i; j++)
  document.write(m++)
 m = m - 2;
 for(k=1; k<i; k++)
  document.write(m--);
 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:

Variable Declaration: The program starts by declaring four variables: i, j, k, and m. These variables will be used in the following loops and calculations.
Outer Loop (i Loop): The outer loop for(i=1; i<=5; i++) iterates from i = 1 to i = 5. This loop controls the number of rows in the pattern.
Assigning Value to m: Inside the outer loop, the value of m is set to the current value of i.
Inner Loop 1 (j Loop): The first inner loop for(j=1; j<=i; j++) iterates from j = 1 to j = i. This loop is responsible for printing the increasing sequence of numbers.
Printing Increasing Numbers: Inside the j loop, document.write(m++) is used to print the value of m and then increment it by 1. This prints the sequence of increasing numbers.
Decreasing m: After the j loop, the value of m is decremented by 2 (m = m - 2).
Inner Loop 2 (k Loop): The second inner loop for(k=1; k<i; k++) iterates from k = 1 to k = i - 1. This loop is responsible for printing the decreasing sequence of numbers.
Printing Decreasing Numbers: Inside the k loop, document.write(m--) is used to print the value of m and then decrement it by 1. This prints the sequence of decreasing numbers.
Line Break: After the k loop, a line break is added to move to the next row.
Repeat: Steps 3 to 9 are repeated for each value of i (from 1 to 5), resulting in the pattern being printed in the browser.

💯 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.
