JavaScript Alphabet Pattern 4

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=65; i<=69; 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

A
BA
CBA
DCBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

var i, j;: This declares two variables i and j which will be used as loop counters.
for(i=65; i<=69; i++): This is the outer loop. It starts with i set to 65 (ASCII value of 'A') and runs until i is less than or equal to 69 (ASCII value of 'E'). It increments i by 1 in each iteration.
{: The opening brace marks the beginning of the outer loop's block.
for(j=i; j>=65; j--): This is the inner loop. It starts with j set to the current value of i and runs until j is greater than or equal to 65 (ASCII value of 'A'). It decrements j by 1 in each iteration.
document.write(String.fromCharCode(j));: This line writes the character represented by the current value of j to the document. String.fromCharCode(j) converts the ASCII value j to its corresponding character.
document.write("<br>");: This line writes a line break (<br>) to the document, causing the next character sequence to be written on a new line.
}: The closing brace marks the end of the inner loop's block.
}: The closing brace marks the end of the outer loop's block.

💯 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.
