JavaScript Alphabet Pattern 7

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

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

<script>
var i, j;
for(i=69; i>=65; i--)
{
 for(j=i; j>=65; 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
EDCBA
DCBA
CBA
BA
A

🧠 How the Program Works

Let's break down the logic behind the code:

  1. var i, j;: Declare two variables i and j without assigning any values initially.
  2. for(i=69; i>=65; i--) {: This starts the outer loop with i initially set to 69. The loop continues as long as i is greater than or equal to 65, and in each iteration, i is decremented by 1.
  3. for(j=i; j>=65; j--) {: This starts the inner loop with j set to the current value of i. The inner loop continues as long as j is greater than or equal to 65, and in each iteration, j is decremented by 1.
  4. document.write(String.fromCharCode(j));: Inside the inner loop, this line writes the character represented by the ASCII value of j to the HTML document. String.fromCharCode(j) converts the ASCII value j to its corresponding character.
  5. document.write("<br>");: After the inner loop completes, this line writes a line break (<br>) to the HTML document. This will create a new line in the output.
  6. }: Closes the inner loop.
  7. }: Closes the outer loop.

💯 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.
