JavaScript Number Pattern 43

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

var i, j, k, m = 1;: This line declares four variables: i, j, k, and m, and initializes m to 1.
for(i=1; i<=5; i++): This is the outer loop that runs five times, from i = 1 to i = 5. It controls the number of rows in the triangle.
Inside the outer loop, we have two nested loops:
- for(j=5; j>i; j--): This loop is responsible for printing spaces before the numbers. It runs j from 5 down to i + 1. The number of spaces decreases as i increases.
- for(k=1; k<=i; k++): This loop prints the numbers in the triangle. It runs from k = 1 to k = i. The number of digits printed on each line increases with i.
Inside the innermost loop, we have:
- document.write(k +"  ");: This line prints the value of k (the loop counter) followed by two non-breaking spaces ( ). The non-breaking spaces are used to create visual gaps between the numbers. This line prints the numbers and spaces on the same line.
document.write("<br>");: After printing the numbers and spaces for each row, this line inserts an HTML line break (<br>) to move to the next line.

💯 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.
