JavaScript Alphabet Pattern 11

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

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j;
for(i=69; i>=65; i--)
{
 for(j=65; j<=i; j++)
  document.write(String.fromCharCode(i));
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

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

Output

EEEEE
DDDD
CCC
BB
A

🧠 How the Program Works

Let's break down the logic behind the code:

<script>: This tag is used to indicate the start of a JavaScript code block within an HTML document.
var i, j;: This declares two variables, i and j, which will be used as loop counters.
for(i=69; i>=65; i--): This initiates a loop with i starting at 69 and decrementing by 1 in each iteration until it becomes less than or equal to 65. In terms of character codes, 69 represents the letter 'E', and 65 represents the letter 'A'.
Inner Loop (for(j=65; j<=i; j++)): This is a nested loop inside the outer loop. It initializes a loop with j starting at 65 (letter 'A') and incrementing by 1 in each iteration until it becomes greater than or equal to the value of i.
document.write(String.fromCharCode(i));: Inside the inner loop, this line writes the character represented by the value of i to the document. Since i starts at 69 (letter 'E') and decrements in each iteration, it will repeatedly write the character 'E' in each line.
document.write("<br>");: This line writes an HTML line break ("<br>") to the document after the inner loop completes. This creates a new line for each row of characters.
After the outer loop completes, the program continues to the end of the script tag.

💯 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.
