JavaScript Star Pattern 2

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

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

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

💻 Testing the Program

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

Output
*****
****
***
**
*

🧠 How the Program Works

Let's break down the logic behind the code:

  1. var i, j;: Declares two variables, i and j, which will be used as loop counters.
  2. for(i=5; i>=1; i--): This is the outer loop. It initializes i to 5 and runs the loop as long as i is greater than or equal to 1. After each iteration, i is decremented by 1.
  3. The opening brace { indicates the beginning of the code block for the outer loop.
  4. for(j=1; j<=i; j++): This is the inner loop. It initializes j to 1 and runs the loop as long as j is less than or equal to the current value of i. After each iteration, j is incremented by 1.
  5. Inside the inner loop, document.write("*"); is executed. This statement writes an asterisk (*) to the HTML document for each iteration of the inner loop. Since the inner loop is controlled by the value of i, the number of asterisks printed on each line decreases as i decrements.
  6. After the inner loop completes, document.write("<br>"); is executed to add a line break (HTML <br> tag) after each line of asterisks.
  7. The closing brace } indicates the end of the code block for 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.
