JavaScript Number Pattern 9

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;
for(i=1; i<=5; i++)
{
 for(j=1; j<=i; j++)
  document.write(i);
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

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

Output
1
22
333
4444
55555

🧠 How the Program Works

Let's break down the logic behind the code:

  1. Declare two variables i and j using the var keyword. These variables will be used as loop counters.
  2. Start an outer loop with the condition for(i=1; i<=5; i++). This loop will run from i = 1 to i = 5, incrementing i by 1 in each iteration.
  3. Inside the outer loop, start an inner loop with the condition for(j=1; j<=i; j++). This loop will run from j = 1 to the current value of i, incrementing j by 1 in each iteration.
  4. Within the inner loop, the statement document.write(i); is executed. This writes the current value of i to the document. Since the inner loop is controlled by j, the value of i will be written j times.
  5. After the inner loop completes, a line break is written to the document using the statement document.write("<br>");. This adds a new line, effectively separating the output of each iteration of the outer loop.
  6. The outer loop then continues to the next iteration (incrementing i by 1) and repeats steps 3-5 until i reaches the value of 5.
  7. Once the outer loop finishes, the entire pattern is written to the document, consisting of repetitions of numbers from 1 to 5 in a triangular format.

💯 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.
