JavaScript Number Pattern 53

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;
for(i=1; i<=5; i++)
{
 for(j=1; j<=5; j++)
 {
  if(i == j)
   document.write(j);
  else
   document.write("&nbsp;&nbsp;");
 }
 for(k=4; k>=1; k--)
 {
  if(i == k) 
   document.write(k);
  else 
   document.write("&nbsp;&nbsp;");
 }
 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:

Initialization: Three variables i, j, and k are declared using the var keyword. These variables will be used to control the loops and determine the pattern of numbers and spaces.
Outer Loop (i loop):
- The outer loop uses a for loop to iterate from i = 1 to i <= 5.
- For each iteration of the outer loop, the following steps are performed:
Inner Loop (j loop):
- The inner loop also uses a for loop to iterate from j = 1 to j <= 5.
- Inside the inner loop, there's an if statement that checks if i is equal to j.
- If i is equal to j, it prints the value of j using document.write(j).
- If i is not equal to j, it prints two non-breaking spaces (  ) to create spacing between the numbers.
Space Loop (k loop):
- After the inner loop, there's another for loop with variable k that iterates from k = 4 down to k >= 1.
- Inside this loop, there's an if statement that checks if i is equal to k.
- If i is equal to k, it prints the value of k using document.write(k).
- If i is not equal to k, it prints two non-breaking spaces (  ) again.
Line Break:
- After the completion of both the inner and space loops, a line break <br> is printed using document.write("<br>") to move to the next line for the next iteration of the outer loop.
Repeat:
- The outer loop continues to iterate until i reaches 5, generating a pattern of numbers and spaces as described above.

💯 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.
