JavaScript Alphabet Pattern 14

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

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j, k = 65;
for(i=65; i<=74; i+=2)
{
 for(j=65; j<=i; j++)
  document.write(String.fromCharCode(j));
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

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

Output

A
ABC
ABCDE
ABCDEFG
ABCDEFGHI

🧠 How the Program Works

Let's break down the logic behind the code:

The var i, j, k = 65; line declares three variables: i, j, and k, all initialized with the value 65.
The for loop begins with i starting at 65, and it runs as long as i is less than or equal to 74. In each iteration, i is incremented by 2.
Inside the outer loop, there is an inner loop with j starting at 65 and running as long as j is less than or equal to the current value of i.
Inside the inner loop, String.fromCharCode(j) is used to convert the ASCII value of j into a character. This character is then written to the document using document.write().
After the inner loop completes, document.write("<br>"); is used to write a line break, creating a new line in the document.
The outer loop continues its iterations, with i increasing by 2 in each iteration.

💯 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.
