JavaScript Number Pattern 40

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

example.html
Copied
Copy To Clipboard
<!DOCTYPE html>
<html>
<body>

<script>
var i, j, k;
for(i=1; i<=5; i++)
{
 for(j=i; j<=5; j++)
 {
  if(i % 2 == 0)
   document.write("0");
  else
   document.write("1");
 }
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

Output
11111
0000
111
00
1

🧠 How the Program Works

Let's break down the logic behind the code:

  1. var i, j, k;: This line declares three variables i, j, and k.
  2. for(i=1; i<=5; i++): This is the outer loop, which iterates from i = 1 to i = 5, incrementing i by 1 in each iteration.
  3. Inside the outer loop, we have a nested loop:
    • for(j=i; j<=5; j++): This is the inner loop that iterates from the current value of i to j = 5, incrementing j by 1 in each iteration.
  4. Inside the inner loop, we have an if condition:
    • if(i % 2 == 0): This checks if the current value of i is even. The condition i % 2 == 0 evaluates to true when i is even and false when i is odd.
  5. If the condition is true (i.e., i is even), the program writes "0" to the document. If the condition is false (i.e., i is odd), the program writes "1" to the document.
  6. After the inner loop finishes its iterations, we have this line outside the inner loop: document.write("<br>");: This line adds a line break (<br>) to the document, creating a separation between the lines of output.

💯 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.
